A native speaker taught me that "resist", "reject", "decline" and "turn down" are more often used on things like invitations, offers, suggestions, etc. rather than people. They are also used on people (e.g. I resist/ decline/ reject/ turn down Peter) but such usage is very strong and is used more in contexts like indecent assaults, stopping thieves, etc.
I would like to seek native speakers' opinions on the above.
Yes, that sounds correct to me in almost all cases. Of course, with English, there are always exceptions!
