Nah, I'm not going to force you to do anything. But I am going to do my best to ensure that this person with a section 8 voucher can use their voucher. I can't stop you from moving out if they move in. I can stop you from preventing THEM from moving in.
And I did answer your question, lol. If you need me to break it down: Saying "I don't want to live next to them" and then listing a bunch of assumptions about why "they" are bad is 99.99% of the time a flimsy excuse for hate. It was when yt ppl used it on us, it is here too.
