Aren’t those Leftists mostly from a Christian background? Tom-
I would argue the opposite. While there is a vestigial Catholicism in some older populations, more European leftists are purely atheist. The vast majority of those advocating pro-immigrant policies would be offended to be called Christians. Those who arent offended would fall into the christian socialist camp which has no correlation with historical Christianity.
I can see that in the upper class ruling elitists, but not in the rest of the European populations.
Their do good, feel good be nice attitudes toward strangers are no match for Islam. Tom
