Your argument is the same one cops use to justify "bad apples": it's not all of us, it's only some of us.

Before any religion starts preaching to their neighbors or "sharing the faith," y'all need to get your own folks in order. You may not demonize LGBTQ+ people, or want to ban abortion, or force others to live under the same tenets as you, but those who wear your cross and share your God do.

So all I can and should do is help to show it's real by the way I live my life, demonstrating love for all mankind, and hope they get the idea. If that much is problematic, I think we've got issues.

I would argue we definitely have issues. You will not change my mind, but religion has done significantly more harm across history, particularly Christianity, than any amount of Christian do-gooding will ever be able to undo. Millions across history have suffered, been enslaved, had their rights taken away, been tortured, and killed at the hands of "Christians," and that includes the modern day. Christian groups are the ones helping to spread HIV/AIDS across Africa because god forbid anyone use a condom, Christians are the ones pushing for abortion bans, and Christians are the ones trying to pull the US into an authoritarian theocracy.

So if you don't want to be associated with the ills of Christianity, you may want to reconsider, in my opinion, what benefit God provides to mankind. Because from where I'm sitting, it's literally zero. The world would be a much better place without religion, and you shouldn't need the promise of an eternal paradise and eternal salvation to, as you put it, "demonstrating love for all mankind." If you can't live that way without "God" telling you, then you're exactly the problem with Christianity.
