People are flagging you because they don't want to listen to you, because you attack them with insults.
Like I said, you are free to insult me. Nothing I can do about it without resorting to violence. However, I can ignore you, and you are not allowed to insult me on property or platform that I own. If I own a platform like a social media, in a free society, I have the right to censor you if I please.
Just like I have the right to silence you if you come into my living room to insult me.
By the way, I've never flagged you.
