Oh really you are all for that huh? First of all, my solution to any problem would never include the words "round them up"...well except maybe for my solution to the conservative problem.
We have a severe mental health crisis in this country, (of which you might be a victim but that is another issue), and we have pathetic mental health access. That is one huge issue. Another big issue is that with all of the cuts to state, city, county, and town budgets (and now federal!), shelters and food programs are sorely underfunded, and private donations are not keeping up. So you may be "all for something" but as a fiscal conservative, those are just words.
Libertarians have ways told me people and corporations will do the right thing once government stops, but I find this to be a big lie.
