Firstly, I am male. When dating younger (Late teens to about 40) religion was never an issue. Politics never really came up. There was only two I was in that I can think of? when there was a presidential election. That is when political issues and politics (Activity) seem to be more live than dead. None of them nor myself held close to the ideology of discounting politics itself it just was that school, office, & friend circles politics were more important.
Regarding religion I was then aligned with an evangelical perspective since changed. Even though none of those dating (All were somewhat long term) relationships led to marriage religion was not a factor for the parting. Parting mainly was due to school / career / life paths like moving away. There was not an interest in a long distance relationship. Perhaps having the internet would have made a difference with that? Interesting for me I dated a Catholic, one of Judaism, a devout atheist, one who did not care one way or the other, and two evangelicals.
When in relationship I attended their place of worship of their faith alignment mainly. I learned and perhaps learned something of synthesis too. Maybe there were not issues because we did not get into the politics of religion, even though there were discussions . In other words there was not antagonism only curiosity and learning.
That probably attributes to my abilities with tolerances between differences religious or political. I am sure it contributed to now having a general open mindset too. I think and feel they had an emphatic impact with my belief(s) of Love too. So, overall I can say the experiences were positive while perhaps today I can truly say they were enlightening.
Footnote: My passion for high performance cars, hot rodding, and NHRA drag racing may have been the 'big' issue. And, with perspectives that could be seen as religious and political. I am an avid ProStock fan over being a Top AA Fuel Funny Car or Dragster fan. ;-) Some were avid Funny Car fans with their view they were much more exciting to watch . . . and the heroes were more flamboyant to them. Plus, Shirley Muldowney was a world champion with a dragster. ;-)
