Those two summing it up pretty well. Furthermore, it's the reliance of individuals' use of cars. Public transportation tends to be praised by that community in contrast from my view, but public transportation is by no means a feasible options in parts of the United States especially outside larger cities.
I'd check out !fuckcars@lemmy.world, I usually just consume memes but they have some articles getting posted as it gains traction.
Racism.
While I was never into it myself thankfully, I let it pass a lot in my family. Being in university changed that though, it just feels too uncomfortable to have my family say racist shit in front of me while I have so many people of color as friends. I still struggle to call out their transphobia though but that is due to my own identity issues.
