The school tax on my house is insulting b/c I don't have kids. Why are people so condescending about it?

My simple complaint about the matter sure does heat people up!! They obviously do not like to hear someone questioning school taxes AT ALL. Do you think it is because they have kids and don't want me making their taxes go up more if childless adults didn't have to pay it anymore? If that is the case it seems like they are happy that I am sharing the bill with them, because they sure do come up with alot of condescending words for me about how "you went to school as a kid" and "investing in the future" and other rhetorical crap. Maybe they feel they are trying to nip a problem in the bud, dunno. I love people, don't get me wrong, but MAN they sure can be selfish. To me, forcing childless homeowners to pay school taxes is socialism. To have to help pay to raise someone else's pride and joy is cruel. People who have kids should pay their own way. On top of it all, they hate it if I were to tell their kids how to behave, but they sure don't mind taking money from me for their education. Double standard??
