Im not "too polite" to not speak up against the errors you mentioned! Quite the opposite!
But calling a dying woman "Idiot, stupidest person at the forum" is not okay under probably any circumstances!
If she is stupidest person there, or an idiot, she probably gets little respect, is easily manipulated, unloved, bullied, made fun of, low self esteem.
If she is a bigot, those can be very tortured, scared, joyless people who were raised that way, unloved, abused, brainwashed etc. Bigots have sometimes been traumatized by the group they discriminate against.
It reminded me of a very bigoted lady I knew, who lashed out at me a lot at Saint Luke's mission of mercy, Buffalo NY. She lashed out men in general it seemed, and constantly ranted about how men are responsible for most wars, rapes, and murders, by far! But she would do it with hatred and beads of sweat! Then she shared with me she was a victim of rape and abortion. I could only pity her and never get angry at her.
I've known racist people of different ethnicities, who repeatedly had traumatic disturbing experiences with some one from the ethnicity they don't like.
The same is true with Religious bigots. That doesn't excuse the bigotry as being less ugly however!
Regarding the Op, point out the errors of the institution and her bigotry yes. Do so in charity, and don't resort to immature vicious name calling.
(In my defense. I didn't know she was dying of cancer).
