Here is one of many things I don't get about these Leftists. Leftists physically and publicly attack Right-wing speaks especially during 2015-2016 Election year. But why haven't they attack other right-wingers before or at least not this vicious before?

During the 2012 election with between Obama vs. Romney, Mitt Romney is Republican and a Right-winger and yet nobody calls him sexist, racist, etc. I would have known. (at least not this large-scale with Trump), no riots, protests, or attacks.
Same goes for John McCain in 2008, again no riots or name-calling. And even Bush 2000-2008. There are small riots but not big enough like in past recent years.

So what, the Obama years was the 'growing point' for Leftism.

Now here where it becomes more of a conspiracy.
I may already mentioned earlier. What if, the Democratic and Republican Party are secretly working together, controlling public opinions, and putting candidates of their choosing for citizen to elect. One of these candidates may be mostly likely to be elected than the rest, but they are all cronies to the "Deep State" (those they call it).

That's where Trump comes in. Again just a theory, if Trump never run for president, the "Deep State" will have no reason to orchestrate the public's hatred for Trump. The Democratic Party doesn't seemed to have much problem with other Republicans.
Again, maybe that because the Democrats are working with the Republicans (or fake-Republicans); they putting their 'loser' candidates and have their candidates chance of being elected.

Back in the 2016 election year, there are Republicans whom are anti-Trump (aka Never-Trumpers) simply because he is an 'outsider'.
