Y'all need a reality check - do any of you really think you can control people or that people can control you? More to the point, opinions are not facts and while they may be valid experiences and viewpoints for a single person, they do not automatically apply to everyone else.
Let me ask a few things -
What is a spell? How do you feel it works? How do you recognize the "end result" once you've cast it? One would think these are beginner questions, but they stick with us as we evolve in our own understanding of how reality works and where magic fits in that picture. Take a moment to actually consider these questions before continuing.
Now, how does a love spell work? How does that differ from wanting to attract new friends after moving or getting a better job? If those spells are not about control, then why is it so for love spells?
The answer to the last question for many people is because of morality. A lot of things go into what shapes a person's morality, and it can range from how they were raised, what communities they developed themselves in and are/were a part of, personal experiences and ponderings, and simple reactions things they might not have given much thought to beforehand.
Because your morality states that magic has a price does not make it so for everyone. Even if you did stumble on a belief that actually is a mechanic of how reality works for everyone, how would you possibly begin to know for sure what it is or that it is a universally valid mechanism?
We cannot claim to know anything beyond what we can prove with scientific method because we cannot isolate all of the variables that are involved with magical, spiritual, and/or religious practices. We can't measure something we cannot physically perceive and even then, the only sensations we get tied to magical practice are because our subconscious has manifested something in a manner that our conscious minds can actually comprehend. Because of this, we cannot experience anything in a truly raw form because we literally interpret everything we consciously experience.
Gengar, let me offer you some other viewpoints on love spells. Whether you take them into account is up to you and I do not claim they are universal truths.
A love spell can be as simple or as complicated as any other kind of working. The only real difference I feel is there is because of social stigma and media portrayal of fantastical claims magic can do. It's all fine and good for fiction, but that is not to be taken as actual magical knowledge - inspiration is another story entirely.
Love spells can be used to attract desired qualities in a person or to expand on feelings that are already there. Many people don't have an issue with asking for aid in love mundanely as well as magically. I find that it's really only the newbie/story fed crowd that buy into taking away someone's free will because of fear mongering feeding into itself. Many people also have fears of astrally projecting because they don't understand how to protect themselves or how the astral plane works if they do believe in it. Few people I know that do practice projection actually believe in the silver cord because their viewpoint doesn't allow for a spirit to actually leave the body as it isn't viewed as a container for a spirit - rather that it is one of many bodies (see subtle body theory for more on that). The entire point here is that viewpoints can be driven by fear, or they can be driven by something else. I believe that love doesn't have to be driven by fear.
If a person truly does not have feelings for someone else, they don't typically "sprout" feelings out of nowhere. There are workings to attract and divert or even alter perception of how someone sees or thinks of a person (though not physical illusions), and it's no different when it is applied to aid in love.
Some examples of magical aid in love that are often looked down on, but are technically still valid be the standard of "everything beyond physical reality and science is subjective and up to personal interpretation, experience, and understanding" are...
"Think of me"
Creating opportunities to speak with someone
Spice up an existing relationship or give aid to a lasting one
Personal oaths to one another (come on, what do you think vows are? That's a popular one and can be seen as a magical practice)
"Help us move past or deal with this obstacle"
Legitimately any consentually romantic endeavor in a mundane situation can be applied magically and we all know how well butting into other peoples lives and telling them what they can and can't do works out when all they're wanting to do is live their lives and they're not harming anyone.
The only way I could see someone being a "victim" of a love spell is if they expressly did not want to be in a relationship with someone and the other party tried to cast love workings/spells/rituals/whatever with their own interests in mind after knowing that. Because honestly? Even in an entirely mundane situation, that's just creepy. No means no, that's the end of that. What I'm talking about besides that, though? That's the majority of what "love spells" are when people refer to them.
