I can honestly say that the Trump supporters (who are conservative Christians) are the most hateful, obnoxious, and bigoted people I have ever met in my life. I can say that with complete confidence because I'm a former conservative evangelical Christian. I was also a registered Republican for 26 years.
During this time, I had a lot of conflict with other conservative Christians over their abhorrent contempt for women, minorities, immigrants (documented or not), and LGBTQ individuals. I also grew up in a predominantly conservative Christian environment (home and town) before that and have known many conservative Christians over the years through church and in places I've lived. In other words, I'm very familiar with them and how they normally behave.
I've shared the following stories in other threads on a similar topic to this one, but I'd like to share them again in response to your post.
The vast majority of my family are evangelical conservative Christians who believe that Trump is a devout Christian and that God sent him to reclaim America. In fact, I'm estranged from these relatives because of how they have treated me since I refused to support and vote for Trump. I have aunts, uncles, and cousins who turned on me and talked about me behind my back. I was uninvited to our family reunion in the summer following Trump's election. A family acquaintance informed me that I had been uninvited because my presence there would have upset everyone else. Unfortunately, the verbal abuse, the bullying, and the harassment increased substantially after I voted for Biden. I blocked the phone numbers of my relatives and former conservative friends, and I blocked a few of them on Facebook. One of the worst experiences for me was having to call the police on my cousin because he threatened to beat me up after he found out that I voted for Biden. My conservative friends turned their backs on me because I don't support Trump.
Lastly, I'm a former member of a Christian forum where the majority of the evangelicals genuinely believed and declared in their posts that Trump is a Christian, that God anointed him to reclaim America, and that God appointed him to purge America of liberals. Lastly, I'm a former member of a Christian forum where the majority of the evangelicals genuinely believed and declared in their posts that Trump is a Christian, that God anointed him to reclaim America, and that God appointed him to purge America of liberals. I was disparaged, called derogatory names, and accused of not being a true Christian whenever I voiced my objection to Trump in response to these Christians. I was called evil, godless, and referred to as a "demon rat." The harassment only intensified after I revealed that I had voted for Biden. I was told I had been demon-possessed, and that's why I voted for Biden. I was spitefully reported by several members, which resulted in my permanent ban with no warning. I reported those who harassed me, but I was told that I was the troublemaker. I received a warning, but the members who degraded and harassed me did not. A staff member who sympathized with me emailed me the day after I was banned to let me know that these members were gloating about how they got me and the other harassed user perma-banned. It was upsetting to read.
