I don't like ANY of the common shit-eatingly-superior, holier-than-thou, smug religious phrases that get bandied about (primarily by Christians, it seems, but that may be to do with my exposure rather than any legitimate trend), few of them annoy me as much as these: 'I'll pray for you', 'I hope you open your heart/mind', and 'Come to the light/truth'. Or anything based on them. They just make my 'STFU and GTFO' meter ratchet off the charts.
It isn't JUST that they're invariably said with the kind of smug self-righteousness of a person arrogantly convinced against all evidence that their view and theirs alone is the right one--it's what's implied. Implied is that not only do I not know any better (and you clearly know much better regardless of your educational background and knowledge base), but that your wish is not for me to be more open-minded and accepting but that my actual brain function is re-programmed to suit YOUR opinions. You don't want me to understand your point of view--you want me to ADOPT it for MYSELF and you're going to ask your all-powerful imaginary friend to do it TO ME, whether I want it or not, potentially against my will. Actually altering the way I think and the way my mind works.
That makes you an asshole, and an insecure one who can't tolerate the existence of different opinions, at that.
