I drove down doordash for a while. Trust me, every driver knows how much they're getting screwed. You'll never be more class-conscious than having 30+ interactions with people as broke as you every day, and seeing every possible angle of fellow working class jobs. You do it for one of several reasons: you want some tiny modicum of control in your life through your schedule, you desperately need the money and it's easy as fuck to get a delivery job, or you started it for one of those reasons or something similar, got good enough to be ahead of the curve, and it's now more appealing than finding something else. The last one was where I was at.
I had done the job enough that I was making $18 an hour, well above the average in my area, and despite needing to pay for gas and taxes on a 1099a, it was still more appealing to keep control and flexibility over my life than to do something else. I could take days off whenever I wanted, see friends during the week, and coordinate my schedule with my fiancee easily. You're very aware that you're getting screwed, but you choose the devil you know, as they say.
Regardless of the stuff about Ada's tone, it seems like your ultimate point was the classic "paradox of tolerance." I certainly do not see enforcing a safe space as policing identity. Regardless of how respectfully done, deciding when it is okay to respect someone's identity is against blahaj rules. The consistent moderation with no room for chipping away at the edges is what attracted me to the instance. This person broke blahaj rules. They may have broken it politely (I disagree. Tone does not excuse content), but they broke the rules. Banning them for repeated invalidation of others' identities is not policing their identity. Your identity cannot be predicated on the invalidation of others. We have every prerogative to be intolerant of intolerance.
Again, regardless of Ada's tone, the point stands. You keep dancing around that. The rules were broken. This user acted inappropriately for the space they were in. They are not forced to use blahaj communities, and chose to do so while violating the rules. They have no right to our safe space if they cannot ensure it is safe for others. I strongly dislike the "just asking questions" polite veneer of your comments while very intentionally dodging the elephant in the room, which is that the user did wrong for the space they were in, regardless if you agree or not.
