I think the scenario is often like this:
A: posts something
B: posts something
C: posts saying that is a terrible/insulting/patronising thing to say
D,E,& F: post saying how dare you (C) criticise A's post
G,H,& J: post saying how dare you (C) criticise B's post
C: posts saying 'I am entitled to my opinion'
K,L,& M: post saying A was quite right to say what she did
N,O,& P: post saying B was quite right to say what she did
Q,R,& S: post in support of C
T,U,& V: post, telling D,E,F,K,L,M they are supporting the wrong person
W,X,&Y: post, angry at G,H,J,N,O,P for supporting B
Z: posts advising everyone to calm down, leave the thread, etc.
C: posts accusing Z of trying to shut down the thread, bar free speech, etc.
Meanwhile: OP sigh's and vows to keep her worries to herself in future
A & B, totally oblivious are busy planning to meet up on another thread.
