If they really believe that considering how often we've seen PL-15s fielded on every other fighter that is compatible with PL-15, then that is fine.
We don't have to oblige or spoonfeed for people's common sense, and the fact you are raising this as a matter makes it sound like to me you are more worried about winning internet fights with people who are stupid rather than simply knowing what's true and what isn't.
My advice is to accept that there are innumerable people who are stupid and foolish and there is no obligation to change or engage them in argument.
having strong soft power bring in more support for your own nation from the world because people vote for grovernment , people affect grovernment policy , do you really think all those nation allied/friendly with US doing it entirely because US control/force them without any kind of love/fanboy from large portion of those nation population ?
lol no ...now you understand why US/west alway promote : "freedom of press" , "internet censorship" , free media 24/7 .
because they are very good at making people around the globe fanboy them (ofcouse minus some place they rencently bomb)
atleast it work fking wonder even in my fking own country (which being bomb to shit by them in the past) to the point today our grovernment basically stuck between rock and hard place . can't start any policy too friendly with china also can't be real "allied" with us/west either because they (US/western) don't even truth us , specially in term of buying military equipment : lol anyone dare to promote the idea buying chinese military weapon system will be shut down right away in fear of riot guarranted happen . even thought chinese military weapon system there day way affordable and better than anything russia export
lol our military buy a bunch of shitty gepard frigate 400 milion dollar each for extractly this reason
and now after a couple of dozen crappy T-90S , 4x S-300 battery our military can't even buy any new stuff anymore because russian now can't even afford to sell or they found out we can't escape them so they demand higher price tags
