Leftist Gun Clubs

Title. I imagine there is no such thing as a "socialist gun club" in Harris county, but my partner and I would like to become responsible gun owners and would like to be trained as such at a range that doesn't have the rebel flag hanging off the wall. Obviously I'm being a bit facetious here (and perhaps a bit closed-minded), but I would like some recommendations for ranges that offer gun safety training that have a welcoming atmosphere toward a certan crowd, or at the very least a professional one. All suggestions appreciated!
