I agree that context is extremely important... so much so that it is hard to overstate its importance in interpretation.
I also agree that in some letters verses and contexts, Paul was expressing an opinion, not necessarily commandments from God directly. Still, as an Apostle his words carry much weight regardless.
Yes, a lot of people do "go looking for affirmation", which is the entirely wrong way to go about interpreting Scripture. In any given large group of people, Christians or whatever, you find some percentage of folks who aren't too bright, or not overly honest in their devotion to their alleged principles.
I've known people who try to "claim" Biblical promises or commandments that were, for instance, only given to the Levites of a certain time period under specific circumstances, and I facepalm internally.
It's a complex business which is why there are priests and pastors, typically a bit more educated on the matter (at least hopefully).
I am a mere layman, but I have studied carefully for half a century... as I think anyone who devotes themselves to a given belief system ought to do.
Scripture should be approached with spiritual humility and a mind open to God, considered carefully in light of the context, time and place, particularly who is speaking and who are they talking to, and why, and handled with the care one shows a sharp blade.
It is regrettable there are many who call themselves by His name, and
do not take suitable care with His word.
