Most people put up a facade to some degree. It's definitely not just an INFP thing and i think the defense mechanism you mention is very common. People just have different ways of doing this, some are very good at it while others are not, and some are more comfortable doing it than others... this may be type related, as the defense mechanism requires us INFPs to neglect things we value deeply.
However, i do think you're being overdramatic in the bolded part. In my experience, most of the qualities you've listed are actually appreciated by a wide variety of people. The only one that's really not received well is being reserved, as it's easily interpreted as arrogance or disinterest. But i'm a heterosexual man and i honestly don't remember ever being criticized for being imaginative, introspective, self-aware, affectionate, emotionally in tune or considerate, even though these qualities indeed do not fit the common male stereotype (except for self-awareness, which really doesn't conflict with it at all).
By the way, how does being reserved fit into that list anyway? To me, being reserved seems like a defense mechanism itself, as it's a way to keep people at a distance. At least, that's true for me. Either way, it certainly doesn't seem to go hand in hand with being affectionate and emotionally in tune.
