UBI, or any other kind of cash based welfare, is not a form of socialism.
But it is American Socialism. Which seems to be defined as "Using tax payer(my) money to give people things or services that I don't want them to have because I don't get/want/need it"
Of course, I've seen people justify this by basically saying "This is my money. I'm just getting it back".
Which is weird since its not just your money, its everyone's money, out into a pool, then given back out. Like welfare.
Edit- wonder if I'd get a check...
