Nice skipping over the failures of Nixon, Reagan and Bush, but you started off by blaming Obama for the rise of Trump, so of course I wasn't expecting to see anything critical of the right wing presidencies over the last 40 years. You criticize Obama for "Hope & Change" but yet Trump is doing the same thing with "We're gonna defeat ISIS" and whatever other non-plans he's putting out there.
I also don't see protesters getting sucker punched at any Obama rallies, and Obama never egged anyone on to commit violence in the name of a political movement, so your "argument" fails there too. Obama isn't/wasn't out there pushing an anti-white agenda (to Trump's all-white agenda), and Obama didn't incite his followers to violence while pretending he didn't do just that very thing. I don't expect to get any kind of coherent argument back on these points, you obviously have way too much hatred of him built up to be able to see reality. In terms of presenting a valid case for Obama causing Trump's rise to power, let me say "IT STINKS!"
