Obese people riding around on scooters really annoys me..

Idk you never know the story. You don't & that's how it is.

I understand that it might be frustrating to see people who appear to have self imposed problems sucking up the resources that were originally designed for those who were not disabled by their own crippling life choices

Buuuttt

People who have severe, crippling food addictions
People who compensate for horrific child abuse by comfort eating and making themselves unattractive as a coping mechanism
People who used to weigh 600 lbs & now weigh 300, lost a shitload of weight but are only halfway there because it takes time & they have joint damage
People who happen to be fat AND disabled, or got fat after they became disabled

Those people exist too

And they scoot

Most people aren't any better. You got your drug addicts, porn addicts, dog fuckers, anti vaxxers, stupids, arrogants, mental disordered smokers, insomniacs. Obese people just wear their addiction on the outside of their bodies, so you think it's fine to hate them. Everyone does.

I'm not a person who believes being fat is healthy, but I am a person who's fucked up a million times, so I don't hate other people for fucking up in whatever way they do.

Maybe try thinking about other people's lives or your own be4 you get all sanctimonious.
