These are pretty basic things I don't like or tolerate and most if not all of them go without saying but just to be clear:

• Transphobia (This includes TERFs: get out of here)
• Homophobia (Again I don't tolerate TERFs. Trans women are women. Trans women can be lesbian)
• Sexism
• Racism
• Pedophilia
• Blatant Ignorance
• Fandom Hate
• Hate in general
• Animal Cruelty
