Out of curiosity, I took a course on the Bible in college, and my professor would have loved this meme.
According to him, Christianity has always counted tolerance as one of their main tenets, but they also completely ignored it from the start. "The biblical definition of tolerance," he would tell us, "was that you might not be happy about people doing things that oppose your worldview, but you were okay with it as long as you didn't have to participate." At the time, that was pretty cut and dry - be chill with other religions, be nice to societal outcasts, don't piss off the Romans, etc. In a modern context, that notably includes not discriminating based on serial orientation, which is where we generally see Christians messing up right now.
Where it really gets spicy, though, is that from the very moment that Christianity emerged as a sect, they were persecuted by the Romans for exactly the same reason as the Jews: monotheism. Christianity was initially a small sect within Judaism, and as a result, both groups were monotheistic and refused to participate in compulsory worship of the Roman pantheon... And both groups immediately started pointing fingers, going to the Romans and saying "no, those guys are the real problem, we're fine!" Even as the sect was still fully coming into its own, that key tenet had already been compromised.
Tldr: A short timeline of Christian tolerance:
Day 1: "We're super chill!"
Day 2: "Man, fuck those guys!"
I once rode a chairlift with the safety bar frozen in place... It was the single most terrifying experience of my youth.
I'm pretty sure that if I'd grown up back then, I would've been dead of a heart attack before I could legally drink.
