So for the sake of argument, I assume you're not trolling and I'll actually answer you. Fair enough?
So let's examine historical "facts" again?
1) Democrats are the ones who enabled black slavery. Democrats are the ones who seceded from the union b/c of slavery. This isn't an "opinion," but historical fact. The Confederacy was in fact, Democrat controlled states. The Ku Klux Klan was in fact formed by Democrats and to this day still Democrat controlled.
Factually again, it was the Republicans who abolished slavery at a great resistance from the Democrats. In fact, not only so, years later, it was again the Democrats who try to stop women suffrage and blacks civil rights movement. Again, blacks and women's right to vote was pursued and established by Republicans. These are not "disputable," but historical fact.
2) Republicans do not crack down on illegal immigration? Who are you referring to? If you're referring to the RINOs, they're called RINOs for a reason right? Republicans In Name Only. If these are who you are referring to, you are correct. As I've mentioned several times, I'm not a Republican. I've said on countless occasions about the truth behind the 2 party system, which is in reality a Demopublican oligarchy.
HENCE, why I supported Trump. Not because he is a Republican, but because he is not a politician. He destroyed the Republicans in the primary and then destroyed the Democrats in the final election. The Republicans are the ones who started the Russian dossier and started the "never Trumper" movement, which later carried on by the Democrats after Hillary's loss. If the Republicans and the Democrats hate him so much, that is a pretty big hint he is something different.
Now, that is the only way I think you could possibly meant b/c the otherwise is saying Republicans under Trump don't crack down on immigration, which then makes it a little strange to accept given the massive anti-Trump protests over the "zero-tolerance" immigration policy and the child/adult separation at the border, along with the building of the wall, wouldn't you say?
