Not the parent - but I think it's because it can be seen as too subjective and too open for debate. Like: Oh, so one person opines that x, y, and z are not for them, let's debate it (or outright dismiss it).
And the resultant debate might well be polarising or destructive by itself.
Without knowing what the parent experienced to cause their take on this type of politeness I'm just guessing, though.
It is interesting because I think I see a cultural thing here too: in some cultures "I feel" and "I see" and "currently" are as firm as "unacceptable until it changes" - just worded in a way that conveys respect for the author. But in other cultures it is read as vacillating. Dunno. Guesswork, as I said.
