While I agree with this, (and people that fall in love in movies tend to be more laodicean with religion and politics more than anything else), it's unfortunate reality that the world especially the USA has never been more politically and ideologically charged and polarized than it is right now, and has been for the last few years. Started with Obama and got worse under Trump and even worse with (F)JB. Interpartisan relationships are becoming even less popular/common than interfaith or interracial relationships these days. You find more people on dating sites saying "don't talk to me if you voted for Trump" or "don't talk to me if you're a liberal" or "don't talk to me if you got [or didn't get] the covid shots" than "don't talk to me if you aren't a Christian" or "don't talk to me if you aren't [insert race here], I'm not interested".
