I guess he also did things like ban evangelism and celebrate and promote Russia's prostitution industry by "providence" as well? Brought back the Soviet national anthem? Erected a statue to murderous tyrant Fidel Castro and personally dedicated it? Having Soviet era statues of murderous tyrants re-erected in occupied territory of Ukraine? Etc., etc.
Christianity is thriving in Russia. Putin has spent billions building churches. There are house of worship of all different sects of Christianity, Judaism and Islam.
What Putin and the Russian government has banned are cults and polluted Western denominations that promote perversions like the LGBT agenda.
