*sadly goes to reset the counter to 0 on the "days since I saw someone shit on the existence of light themes" sign*
I think on average I see this like once a week.
I cannot see dark themes at all. And it's a hell of a thing to see this hostility not just to a software option but to my own existence and qualities as a person who uses this option. Like I've seen people say you have to be a psychopath to use light theme, which is an awesome way to double up on the ableism!
