"Your average Christian" depends on where you live. I have "christians" in my family, in my neighborhood, at work, what one would likely describe as average around here, that have expressed at minimum a denial of the humanity of those who are different from them, seemingly instituted or encouraged by their "Christian" culture. I know this isn't all christians, but it seems like where I live, the churches that preach inclusivity are few in number and slim in attendance, and although still not a majority, there are more that preach AGAINST inclusivity, and the predominant culture among most christians regardless seems to lean in that direction. In the lead up to the 2024 election, a number of "christians" close to me expressed extremely violent potentialities should Trump not win, pointing directly toward acceptance and secularism as their motivations and justifications.
You have expressed that things would be worse in the world if it would be some other religion. You think a world where any other religion holding a majority would be worse, is that what you're saying? That is quite an assertion, and I'd like to see you prove that. Imagine if secular humanism were more central in people's lives... What a world we could have.
Edit: I do live in a pretty shitty place, to be fair, haha
