If you want to be a dickhead to everyone around you because youre terminally ill and in pain, you can certainly do that. Thats your perogative. You dont have to give anyone grace or be kind or be nice. You dont have to respond maturely to criticism, you dont have to respect other people's identites. This is the "do what you want forever" website, after all.
But dont expect people to sit down and take it. Dont expect people to stick around you for long, either. There are millions of abusive, bigoted shitheads that die alone in care facilities everyday in this country, because sticking to their assholerly was more important to them than their friends and family. If that sounds harsh, yeah, thats the point. Theres really no way to cushion something like that when its a matter of life or death. And i would never even mention it if it wasnt morg's number 1 defense to deflect all criticism, but here we are.
So yeah, do whatever the fuck you want. Tell me to suck puppy pubes because i corrected you gently on someone's neos. Go on rants about how you cant trust any trans women on tumblr. Say slurs for disorders that you dont have and therefore cannot reclaim. But dont cry harassment and ableism when the natural consequences of you being an asshole come to bite you in the ass.
