Oppression, degradation and ostracization.
In a world where 90 percent of the population cannot even see their own privileges and problems they cause, everything that is against the norm is considered extremist.
Oh, you don't want to pick dead pig parts off your pizza? Why do you have to be so extreme?
If someone picks an argument with you, and since you are actually educated you are "forcing" your "opinions" on them and so now you are extreme.
Tell a fact? Extreme.
Destroying harmful objects, is extreme.
Because you ethics and morals are completely inline with your behavior, you are extreme.

It's NEVER the person who kills for five minutes of satisfaction that is extreme.
It is NEVER the person who has decided to pick a fight with you during dinner that is extreme.
It is NEVER the hypocrite that is extreme.
It is NEVER extreme to kill for money.
Acting purely on your opinions, is NEVER extreme.
Oppressing people who are not following the norm is NEVER extreme.

So what's the point of it all? It's to get activists to SHUT UP. So the victims will have no voice. Its to make fighting for the oppressed seem dangerous or stupid. It's to give people an excuse not to give a fuck.
Familair?
"OH I don't want to be a hairy man hating feminist!" And now that person has an excuse to overlook inequality between men and women.
So shut it to hell, how the hell would you even know if you're not willing to learn?
