If there is something you particularly study, you can apply for a coven on this site, with that path of study.
Only serious members are accepted into covens, so you will not have to worry about all of those children, because that is what they are, speaking nonsense.
To find a coven that suits your needs, click on the group forums and read through the covens and read what they are about. Unfortunately,, most covens today are not very active, but you can still join one and post and speak to others in that coven. What I mean by "not very active" is that many members of a coven do not sign on or do not post, making the coven very slow. But some are actually re-forming and are getting back on their feet. So I would look into a coven and join one.
