Cash is gay but the type of gay who's in a transparent closet. IE not formally out except for a small circle of friends.
Dax only found out that Cash was gay recently. Hence why he's suddenly turned into a huge liberal SJW type; he wants to show Cash he's an ally and down with gay people.
Cash IS embarrassed at Dax's virtue signaling but tends to let it slide because he is happy Dax is OK with him being gay/willing to keep quiet since Cash's family are homophobic.
It's also why FTR merch has had the rainbow iconography as it represents Cash's gayness without him coming out and admitting that he is gay.
