What you call "hostile" is usually just walking away and not putting up with abuse and/or supporting those people who are abusing them.
For example: it is considered "hostile" if people stop seeing a TV-show because they don't want to support a transphobe or sexist actor/host. Well, I've news for you, that person is not entitled to support.
Another example, people like you consider that progressives should date them even if the values of people called "blue" include things like misogyny or homophobia or racism, which are values abhorrent by them. So apparently, progressives aren't allowed to date people that share values with them.
Neither are allowed to talk and express opinions that "blues" consider wrong, because that is considered "hostile".
I think the real problem is that regressives (which are a subset of conservatives) are used to oppress others and have others remain silent and forced to help them. So when people turn their backs on them, they feel that people are being hostile.
They aren't, they are being neutral. They aren't attacking you. They aren't literally beating or killing "blues" like "blues" literally do to women, homosexuals, transexual, blacks and a long list of people literally being abused.
But if you want to go the "political racist" route, I want to remind you about how in US "reds" or communist were literally put in jail, which I haven't see happening to "blues".
People aren't walking away because others are "blue", they are walking away from the abuse you throw their way so they can stop suffering abuse. You should be grateful they just walk away instead of treating you the way you are used to treat them. That would actually be hostile and even more hostile if they also expected you to be nice after that.
If you treat someone badly, it is normal that the people you have treated badly doesn't want anything to do with you. So what you call "political racism" is basically the expected outcome of your politics which include things like "letting poor people die without healthcare", "looking the other way when people abuse blacks/homosexual/women", deny personhood to woman, and a long, long list of things that decent people find appalling.
Actions have consequences, even for "blues".
