I honestly can't remember a "All INFJs of TypC Hate on Mane" thread on this forum.
That being the case, what caused this pattern to emerge?
Why might INFJs here feel compelled to, as you described above RETALIATE against you?
Well, by definition, RETALIATION is an effect. the cause of which is being PROVOKED - and in this case - by whom?
That would be YOU.
I understand that you had some seriously hurtful events to deal with your INFJ ex-wife and issues with her not allowing you access to your Step-son after the divorce, but that does not justify hostility towards every INFJ alive.
You're better than that.
Let the past be in the past, for if you let it sour your present and future, then you give it far more power over you than it ever was supposed to.
Free yourself, for your own sake.
Just my .02.
