Everyone they know hates Trump. Everywhere they go for their information, it's anti-Trump. If there's even a hint that it's not anti-Trump, they cancel it very quickly. They have curated their bubbles very very nicely. No contradicting information ever comes through. They don't have to scramble to find another social media service because they'll never get banned from any. They don't have their GoFundMe's shut down, that only happens to bad people. Everything is just spoon-fed to them 24/7 and anything that could pierce the bubble is utterly ignored.

Any pro-Trump people that they might know, who wants to stay in their good graces, would never tell them how they feel because they know what the reaction would be. They never have to worry about one of their politicians getting arrested or involved with a major scandal because that just doesn't happen. Any any scandals that may be whispered about are just part of the vast right-wing conspiracy or Russian propaganda, and they know this because that's what the media will tell them every single time.
