Ive made two converts that I know of by pointing out that they object to socialized healthcare, socialized clothing and socialized housing and socialized food. All of those are at least as much a basic need as schooling. Its hard to convert the indoctrinated but not impossible.
Yeah.........Don't you Socialists touch my "Food, Clothing and Shelter".........but go ahead and keep my offspring under your thumbs for twelve or thirteen years.....!
I trust you....because you're from the 'gubmint....and are here to help......right?
