Man thats just too much the hell, tf is up with tealand people, they probably didnt even know you were gay but just like calling anyone they dislike faggots cuz to them being gay is still a bad thing like how calling someone gay was an insult 20 years ago
If the maybe somewhat competent adults involve the soccer kids' likely equally as dumb parents I doubt anything good could come from it, still dont keep this to yourself
Insulting and threatening to that point or even to get killed regrettably happens all around the "civilised" world and because of that little gremlins repeat it without even understanding it. Even if some adults turn the blind eye on it, it is something you should report first to the teachers (something as simple as "these cliques/group of students harass me verbally this agressively everytime they get the chance, please do something") and afterwards to local authorities.
