“It may not be a wise one though.”
There is a difference between cultural “imperialism” and otherwise promoting standards of international behavior and leading by example. We can promote what we think collectively is best about our Republic, leading by example, but that is never in the details of specific social movements, such as the socalled “LGBT” agenda. That movement is far, far, far less about “rights” than it is about demanding “social recognition” by group identity which says absolutley zip about personal character, and the use of group identity promotion is in fact to promote persons REGARDLESS OF their personal character. Black Democrats are promoted BECAUSE they are black, regardless of their character. Most black Conservatives stand out because of their character regardless of being black. The same analogy is true for the few “gay” Conservative/Libertarians who served Trump in major appointed positions, NOT “because” they were “gay” but irrespective of that fact.
To promote transgenderism has zero to do about “promoting” America and is not “cultural imperialism” as much as it is merely political imperialism on behalf of a single minor political narrative, not on behalf of “the country”. Such agendas that won’t to be promoted should be done on their own, privately and socially, not via the government.
Can you imagine the outcry if the American Christian evangelical movement was being promoted by the state department, and it is cdrtainly a far larger cultural movement than transgenderism. The entire U.S. Left and 100% of their media would be up in arms.
Of course, because Evangelicalism is the culture of Proles, not the ruling class.
