I'd be wary of laughing it off, the Tories in the UK are currently on this path, something that would have been seen as risible only a decade ago. There are several types of conservative behaviour, and cultural - the "barstool" conservatism - tends to be entrenched in the working class, and is what the Tories have been successfully banking on. In the UK, the issue has been the traditional working class party, Labour, have been effectively captured by more middle class concerns, who tend to be in the top decile of earners and oblivious to the fact the 90% view them in much the same regard they view the 1%. The general response from a lot of middle class Labour voters has been to blame the working class voters. Which has predictably alienated them further.
Working class party means socialist. Everybody spread the word that the GOP is socialist now so the good conservatives of this nation don't mistakenly vote for these dirty commies.
@Ebeneezer Goode No contest on any of those points. Both the Republicans and the Tories have built their success on appealing to the social sensibilities of average people. But the Tories are far to the left of the Republicans on economics, and thus they now have their strongest coalition in decades. I've argued this in other threads. Progressive economics and social conservatism would be a winning coalition in the US. Unfortunately Trump was too incompetent to deliver on that combination, and governed like any other Reagan Republican.
With cultural conservatism I agree with you, social conservatism is a little different and tends to originate from religion rather than the more communal cultural version. I'd be cautious of that, it risks resurrecting the US' more Calvanist aspects, which would be a nightmare for rights around same sex relationships and trans. Identity politics is in need of an antidote, not an antithesis
