Ok in all seriousness though: yes I agree with you. Fe is oriented towards groupfeel and puts people into groups based on objective ethics-related cues, which highlights differences and good or bad traits they perceive them to have. It can be very “us vs. them” at times based on ideology or some external group markers. There may be some more initial cognitive attraction towards that because of “Fe”. However it would be inaccurate I believe to imagine that other types don’t also engage in controversy and us vs. them conflict a lot too. Likely just as much, but for other kinds of reasons.
