Colonization still happens, but I think it matters that it happened in the past too. I would say that one of the most prominent recent examples would be the American invasion of Iraq. There are many political and economic aspects to the invasion, but one cultural angle is that it was widely supported by religious conservatives due to their opposition to Islam. American leadership was ghoulish in their own way, and to incompetent to actually colonize the country, but many of the literal footsoldiers joined the military to "get back at them for what they did to us", although as we know, none of the 9-11 terrorists were Iraqi.
Another example that springs to mind is the ongoing homophobic and transphobic hate crimes. One specific example would be the Pulse nightclub mass shooting. I would suggest that most American Christians don't support death for being gay, just the same as most American/Western Muslims don't support death for burning the Quran, but in other countries where religion overlaps more with politics, both of these can be considered serious criminial offenses.

I only mean to suggest that both religions have a bit of bloodthirst in them, which doesn't apply to everyone, but is certainly comparable. We can go deeper into the details, I just felt like you were giving Christians a bit of a pass that they don't deserve.
