Here are my top 5:

• Being on their phone too much.
• Being willfully ignorant.
• Believing in religion.
• Using proprietary social media apps (e.g. Instagram, Snapchat, Facebook).
• Using non-free BIOS firmware / non-free software.

Being smarmy. I can't stand people who are ready to manipulate anything out of people as they do it with their smarmy smirks.

Everything.

Secretly, I'll pass judgement on someone until I realize I know nothing about them and would be unhappy if someone judged me without knowing anything about me. Then I judge myself for being judgmental.

being judgey assholes

Casual fossil fuel use. Not work related shit, but asking me to drive an hour to you to chat because you won't learn discord is demoralizing. I know that it's not a big source of CO2, but it adds up and the same people who do it also throw food out, don't fix anything and don't demand more action from their politicians. They RP as revolutionaries, but don't do anything.

I judge anyone who misses the letter G out when they say the word "recognise".

Not putting the toilet seat down.
