Putin is religious?
Yes, I'm sure he attends mass every day and donates his time and money to charity to boot.
Putin is as religious as Hitler was. Hitler declared himself a Christian, only, he had no use for the Bible EXCEPT for the verse that said Jesus drove the Jewish money changers out of the temple with a whip. He said that the rest of the Bible was bunk.
But in terms of being moral and preachy, none do it better than secular Leftists, and with impunity since it is PC to do in both government and corporate America. Now you can get as preachy and, in your face, as you want about how you should live your life, so long as you don't mention the "G" word.
In fact, you can even declare yourself a Christian and a Leftists, like Biden and Warnock, so long as Jesus bows his knee to the DNC by declaring such things as abortion virtuous and a fundamental right to your existence.
