It's not that big of a claim. Sure, during the Crusades Christianity became a tool of political force, but for the first several hundred years of Christianity's existence, it itself was politically persecuted, especially under Nero and Diocletian. So it had to rely on missionary trips and word-of-mouth especially via ancient trade routes to spread. It was basically just another underground "slave religion"in the Roman Empire before it was finally legalized in 313AD.
Even after legalization, Christianity was just tolerated like all of the other religions in Rome at the time.
There seems to be a lot of misunderstanding about my meme: this meme is a lampooning of the far-left radicals around the West who have stupidly (or purposely) opened their borders to unchecked, unregulated, mass immigration - effectively inviting the most extreme ideologies in the world, that have directly lead to terrorism and violence, into otherwise peaceful nations. Also, it highlights the narcissistic gaslighting those on the Left do who use insults and fear, labeling people as "racist" or "xenophobic" or "Islamophobe" to manipulate them into silence while watching their homes be turned into targets for dangerous, radical extremist violence.
Those "leaders" responsible for this crisis currently plaguing multiple nations in the West, spit on the faces of the citizens who trust them and cast suspicion and doubt on normal immigrants and asylum seekers into the hearts of their fellow citizens. May they burn for what they've done to their nations, their citizens, and to innocent immigrants.
As much as I wish I could, I cannot control people from being wrong. Thos cartoon is supposed to atrack the incompetancy (or downright evil) of far-left, open border policies, and deregulated immigration which actively invites extremists into otherwise peaceful nations and also actively inflicts suspicion on regular immigrants and asylum seekers in the eyes of the public
