I'll grant that the objectification of people is wrong from a consequentialist perspective, barring any redeeming factors. I'll also point out that any action (like supporting a given field of study) that has negative consequences which exceed the positive consequences is immoral from a consequentialist perspective. I'll refrain from making any claims about whether supporting any specific field is a net negative.

No, I think that actions are 'justified' when the expected consequences are in accordance with the values of the actor. Actions are only 'moral' in my view when they are made with the mutual consent of all participating actors. A decision such as destroying one's own private property and making oneself sad as a result are moral but unjustified in my view; from a consequentialist view, that would be immoral.

Unjustified actions are not always immoral, but do indicate suboptimal decision making and poor mental hygiene. Being able to recognize those decisions in oneself and others is important.

I rage against the sexism that results when the possible fact "There is a difference between male and female brain chemistry with this result" becomes "This is proof that one sex is [universally|locally] inferior". Not because I have a moral obligation to prevent as much harm or create as much good as possible, but because I have a philosophical need for people, who are metaphysically equal, to be treated as metaphysically equal.
