Sounds like you're overreacting. It doesn't really matter where the customs come from. Some of the months of the year are named after Roman gods or Emperors (July = Julius, August = Augustus), the days in the Romantic languages are from Roman gods also (Vendredi = Venus). It's a glimpse into the past, accepting social customs doesn't mean you have to believe in the original doctrine. The longer things go on, the more you'll see the things from religion that are poisonous will fade out, like slavery and homophobia. What we're left with is history. Something for our descendants to look back and laugh at.
Think of the way you view Greek/Roman/Norse gods. One day, we can all hope that people will view current religions in the same way.
