In what way would barring felons lead to barring gays? People use the words “slippery slope” to make their point, even though it’s literally the name of a logical fallacy. You have to show HOW one will lead to the next, not just say “a little might lead more!” That, exactly, is the fallacy. Textbook.
I don’t accept the argument that as long as 51% of people vote for something, it should be good to go. We have a constitution, you realize, and you need more than that to change it. Is the constitution suppressing democracy? You’re talking about a kindergartener’s view of “majority rule,” not American democracy. And thank goodness, because I heartily believe that 51% of people would vote for some ghoulish shit, like boiling immigrant children in oil. And there you’d be, shrugging and saying “ahem - 51%, people.”
Go off and think it through a little better. I’ll be here when you get back.
