Thoughts on having real world groups in far flung futures?

I have a world set thousands of years in the future. Humanity reached for the stars and settled planets. They brought various religions, nations, and other groups.

I wanted diversity, so I had different space orgs (Nasa, CNSA, ESA, etc) all settle their own colonies and be somewhat isolationist, that way I avoid convergence.

On my cowboy vs indians planet, I want to bring in the protestants vs Catholics conflict.

Do y'all think this is out of line, or perfectly reasonable?
