I think...
pop culture has diffused the word racist to a point that some would think anyone that supports a certain political party is a racist, or any number of other words. This means that anyone that supports anything that someone on twitter has deemed "racist" now has to defend other "racists" since the nuance is all gone. I am sure most people hate white supremacists but since people that may support walls or no affirmative action get lumped in with white supremacists it became a hot button issue.
Xenophobic people, white nationalists/supremacists and people who deny the current state of race relations in this country are usually on the same continuum. Where you draw the line on who it is okay to call "racist" is debatable, but it more or less comes down to human's tendencies to put people who are different in another group and then treat them differently (usually worse, sometimes just showing indifference.)
While Hollywood has a historical propensity for taking an issue that needs to be addressed, producing art that can help affect the culture of the country and then eventually start trying to exploit it for monetary gain.
My best guess is that most people get offended by any art that addresses race relations say "this topic is so trite" because they don't want to express how uncomfortable it makes them to talk about these issues. Watchmen is a work of fiction, but that massacre in Tulsa happened, and its depiction wasn't even exaggerated significantly. The "white supremacist" storyline where the influence of those groups ebbed and flowed throughout history is also something that happened and is literally happening right now in this country.
Any subject can be covered poorly and/or exploitatively, but I don't know how any reasonable person can call this storyline trite or bad or not related to reality. I suppose in their mind we shouldn't be allowed to talk about reality if it reflects poorly on white people.
People are complaining about a show that depicts things that have happened and are happening. I'm not sure how a person can reasonably justify that without just admitting that it makes them uncomfortable.
