It's possible, yeah, but you have to be particularly insensitive to both verbal and nonverbal rejection cues in order to be willing to do it more than once.
Ever pitched a controversial opinion to a group of peers? You'll find that a lot of people look down at their hands, or away from you, or at each other with a blank/expectant/fearful face.
This can depend a lot on the particular peer group and the opinion holders position within it. Plenty of people will state proudly that they hold certain controversial views (often borderline racist etc) but they tend to surround themselves with people who either hold those views themselves or by people who are meek enough to accept the views without resistance so the social penalty doesn't apply.
