Define "freeloading" for me. They don't have access to big social services (TANF, SSI, etc) due to not having documentation, roads are funded through fuel taxes as far as I'm aware (so if they're pumping gas, they're paying for the roads), dog parks are usually paid out of local sales tax (again, only as far as I know, I live in GA and we're a fucked up state a lot of times).
Income tax is a big one, but not on a small scale (like municipal level)... Hell, I haven't ever had a local income tax that I can remember.
I'd say it depends, do you believe that you could live as a vegan? Not everyone can, and nothing is wrong with that. I view some animals as yummy and others as not, I've never tried eating an oat tree, but I'll tear up some carrots.
I like the idea that consciousness is experienced by all living things and am totally okay with a certain amount of it ending during the natural progression of my life.
