1. I think you're WAY off on the percentage of racists. Using obscure web sites like '4 chan and 'gamergate' as any kind of proof of rampant racisim among Republicans is just crazy talk. I imagine most of those trolls aren't even Republicans and probably don't even vote....and there aren't nearly as many as you're imagining.
Yep, it is all my imagination. 4chan and 8chan are some obscure sites nobody has ever heard of except White Nationalist Terrorists, Donald Trump and Don Jr who have posted memes from there on several occasions.
Here are 8chan's Numbers:

Here are 4Chan's numbers:

Keep in mind those are 8chan's numbers after being down for several days this month. 4chan's numbers are also underrepresented because they split their traffic between their .com and .org domain. That number above is just the .org. So there you have it. They are in the top one percent of websites in the entire world. The numbers are from similarweb.com if you want to verify them. More on Gamergate's ties to the conservative movement at the bottom of this post.
2. President Trump is most certainly not a racist execpt in your mind that has been ravaged by Trump Derangement Syndrome.
Nope, he is a racist because he says and does racist things. I suspect conservatives are willing to engage in such fanciful arguments that Trump isn't a racist because if they admit that then they would have to admit they were racist for continuing to support him. Lookie what popped up on my newsfeed as I wrote this reply.
President Donald Trump on Tuesday criticized Jewish Americans who vote for Democrats, saying "it shows either a total lack of knowledge or great disloyalty. The remark led critics to argue the President was dabbling in the anti-Semitic trope of "dual loyalty," which questions the loyalty of Jewish citizens. Source
Funny how you don't mention exactly what that question was in your screed. The question was "Are you a United States Citizen?"
I have posted the question in its entirety on this forum before. That is not all it asked. However, it doesn't matter what it asked as the intent according to the guy that formulated the question and the Republican officials he corresponded with was to discriminate against legal Hispanics. If you are not disgusted by that and you continue to twist and turn more than a contortionist trying to justify racially rigging the vote, you are a racist.

Gamergate's Ties To The Conservative Movement From Don Diego's Favorite Source Vox.
Trump’s anti-political correctness rhetoric during the 2016 presidential campaign and beyond appealed to many gamers, particularly those who took part in the Gamergate movement of 2014.
Gamergate began, as my colleague Todd VanDerWerff has written, with two separate issues: the treatment of women in gaming and the ethics of video game journalism, with criticism of how much coverage goes to social issues featured in video games as compared to the gameplay itself. The launchpoint centered on a woman game designer and her ex-boyfriend, and her alleged relationship with a writer for an influential video game website. But over time, the movement seemed to metastasize into one dedicated to trolling.
In their quest to defend video games from the threat of censorship by so-called “Social Justice Warriors,” Gamergaters doxxed their opposition, harassing women on Twitter and even driving some of their targets from their homes — a tactic that the alt-right would later use against anti-Trump voices. As one of Gamergate’s biggest targets, Brianna Wu, told CNET in 2017, “GamerGate was the canary in the coal mine.”
Some Gamergaters (particularly those who joined the movement to protest “political correctness” in video games) contributed to the rise of the alt-right, a loose cadre of populist-leaning reactionaries and some conservatives who deemed the traditional right wing as ineffectual.
They found a voice in Trump, particularly after former Breitbart News chair Steve Bannon took a role in Trump’s campaign. Many of Trump’s biggest online supporters came into pro-Trump activism from Gamergate. These include people like Mike Cernovich, who called Gamergate “the most important battle of the culture war this century,” and disgraced former Breitbart editor Milo Yiannopoulos, who attempted to “legitimize” the alt-right within conservative media and take it (and its racism and anti-Semitism) mainstream.

I suspect you are one of the older conservatives that has no clue what Gamergate was and its ties to Trump and the larger conservative movement.
