Everyone is nimby when it touches the most valuable thing in their life. You'll turn nimby once you buy a house. There's no lie, anyone will be against a landfill or skyscrapers near their house. If you think otherwise, you're lying.
I own a house and I don't give a shit what happens on the lot next to mine. Not my property, not my right to complain. So you're wrong. Also kind of rude for calling people liars when they disagree with you.
What if next door they put in a combination slaughter house and sewage treatment plant? What if they built a gigantic speaker pointed in your direction?
Or made a home for wayward youths who live yelling slurs?
There's nothing wrong with nimby.
