I think @mailadreapta is correct that part of the motive on the conservatives’ part was to point out the contradiction in their progressive and liberal opponents’ actions. Up until this election, the progressive juggernaut had pushed so far forward (or ‘forward’) that it had started throwing white gay men under the bus, which, combined with the fact that the left/liberal plan is to import people of an ideology which is actively hostile to LGBT people wherever it rules, and at rates so high that it risks displacing the native population within a handful of generations, without doing what is actually necessary to defang and atomize that ideology, and constantly making excuses for it, created an opening for attack.
In this case it’s no different than left-wingers pretending they give a sht about countries or the army. The “lul fuck u army’s just an imperialism machine” response may be more honest WRT their actual beliefs.
For my part of course, I disapprove, much like I disapprove of terminating that military-service-for-citizenship program which is apparently ending soon.
It puts me in an awkward spot. Last administration, I spent a lot of effort trying to defend the Obama Administration even when it did dumb things for which there was no defense, and honestly after a while I gave up on that kind of party loyalty because pols will betray you every time.
