I'm pretty sure that "returning to the root Slavic religion" would involve offering massive cow sacrifices to the thunder god Perun in exchange for long life and prosperity. Not sure if that's what you had in mind, though!

There were decentralized Christian-like religions like Bogomils (Cathars in Western Europe) in south Slavic parts before modern centralized religions. Maybe those would work better with Slavs who seem to not organize well around centralized sources of power.

Many of us offer sacrifices today, too.

In most Slavic countries, it is customary to slay and eat a pig on certain holidays, like Christmas and our Slava.

In the US you kill turkeys for Thanksgiving. How different is that compared to other "sacrifices"?

Sadly, we don't offer our turkey up to any thunder god. It's even traditional for presidents and governors to pardon a turkey. Blasphemy!

We do it for the fun and food, not for some pseudo gods.

You can colour it any way that you like. Many Americans would likely baulk at the idea of a turkey-less Thanksgiving. It is a central theme of the holiday. What else is it, if not a sacrifice?

It's food and fun, not sacrifice.

We can do it for both. Why not?

Perun is a "pseudo" God, as much as Zeus was a pseudo God.

And if they are pseudo gods, then Jesus Christ is a pseudo God, too.

Gods exist as long as people believe in them.

Because we mostly don't like gods, at least here in CZ.

Yugoslavia pre-1945 had nothing to do with communism and socialism - it was created explicitly as a pan-South Slavic state. It ended up being dominated by Serbia, though.

I assure you, it is not.

Many Slavs feel the same.
