None of those people will say that it applies to all people who partake in pornography. Your blanket statement falls flat.
In addition there is a difference between the porn industry and porn itself. Porn can be created outside of the industry. I would say that the industry is destructive. Hence why sites like Onlyfans exists where people can be in charge of their own product without the abuse.
As for promiscuity not promoting all those things that you mention, it doesn't need to. As long as someone had other aspects of their lives to promote that then there isn't a problem. Also, decency is a stupid subjective concept, which means different things to many people.
If two people have no feelings involved when having sex then good for them.
I would say that your religion very much promotes tribal selfishness, callousness and hurt feelings through self righteousness. Yet you partake in that.
