When people get mad at other people saying that something they did was racist/sexist/heterosexist/cissexist/whatever.
I don’t get it…
It’s like…

If you were hanging out with your friend and your friend turns to you and says, “Hey I don’t know if you noticed but you just stepped on my foot, can you please stop”.

I am guessing most people would say, “Oh man, I’m sorry!”, and maybe watch where they were walking a little better.

You probably would NOT:

Yell at your friend for accusing you of stepping on their foot.
Deny that you had stepped on your friend’s foot.
Argue with your friend over how you step on everyone’s feet equally, so it shouldn’t matter.
Insist that you didn’t step on their foot that hard, so it couldn’t have hurt them.
Get offended over the implication that the way you walk is wrong.
Say “Okay, but what about MY foot?”
Step on your friend’s foot more to show how it isn’t even a big deal and nobody cares about people stepping on each others feet anymore.
Reference that one time when your friend stepped on YOUR foot and you didn’t complain.
Tell them you didn’t mean to do it, so you’re not responsible for stepping on their foot.
Deny that your friend has a foot.

I mean sometimes the person isn’t even a friend or someone you know but that doesn’t matter, don’t fucking step on people
