You are aware that rule was changed so the apostles could preach to the Gentiles, right? Before then, Jews weren't supposed to interact with Gentiles unless they were captured (and if you read accounts from the people who captured them [these are not found in the Bible], you'll see that they tried to adhere to this rule (excluding the Samaritans, who most of the Jews didn't even count as Jews anymore). After Jesus died, God wanted to send Peter to Cornelius' house, and so He allowed him to eat the foods which had been considered unclean. This was also a part of the Old Testament Law being replaced by the New Covenant. This is a different standard being applied based on the time. It still bears no resemblance to suddenly changing His stances of righteousness based on His actions just to gain human approval, which, as I have stated, God clearly has no need for. In order for that situation to be even remotely similar to the leftist comparison, God would've needed to have said that "all beings cannot eat meat, as it is an egregious sin" but then one day decided to eat meat, and when He gets caught, He then says it's perfectly fine, but then goes back to saying it's a sin when He's done.
That's a nonsense hypothetical and God would never do that. But if anyone was dumb enough to put a gun to my head, I'd slap it out of their hand.
So I take it you'd be cool with all the bad things that happen in Revelation? Because I sure wouldn't want to be on the wrong side of that. Also whatever you think about God, the devil is billions of times worse. It's from him that humans got the idea of treating women like property. It's actually because of him that males have leadership over their houses. It's because of him that slavery exists, and without him, there'd be no animosity, no murder, no hatred, no nazism, and certainly no communism. You ever wonder why the anti-religious left is completely supportive of Islam but despises Christianity, even though both religions are not pro-LGBT? (When I say "supportive" I mean they give them minority treatment; you can be "racist" toward them [whatever the heck that means], and putting Muslims on TV is a win for representation.) The devil is not anyone's friend, and certainly doesn't care about you even if you intentionally ally yourself with him. And I certainly don't care to join him anywhere.
