How would you react to a gay person who found you TOTALLY repulsive ?

 Absolutely.

A few others here have expressed similar sentiments, and I'll add my voice to it.

There is ZERO need to express a negative opinion on something unless:

A)  You were specifically asked for your opinion

B)  You're a professional movie/art/food critic, opinion columnist, or Judge, and it's your job to pass an opinion on that specific thing

C)  The thing upon which you are expressing your opinion is in some way not merely unpleasant to you,
but OFFENSIVE or damaging in some way, and something needs to be said.

D)  You are participating in a forum or blog where people specifically come to air opinions, whatever they may be...
...and even then, as Pyrrho pointed out, there's really nothing constructive being accomplished by offering a gratuitously negative opinion
on something that is hurting no-one.

I slightly disagree with what you have stated.  I think in the case of something put out for public display, like a movie, it is fine for people to express negative opinions of it.  But the personal appearance of people who do not put themselves on public display, is a matter that is normally best left alone.  Just to be clear, going to the store to get a loaf of bread, although one is then in public, is not what I mean by being out for public display.  One is then out for a loaf of bread, not someone shouting "look at me!" to the world, as is effectively being done when one makes a movie.  If someone chooses to be the focus of public attention, different rules apply than to those who do not make that choice.

That IS what I said:

" B)  You're a professional movie/art/food critic, opinion columnist, or Judge, and it's your job to pass an opinion on that specific thing "

(IE: movie critics can criticize movies....they may not criticize passerby on the sidewalk)

I was not in any way suggesting that just because you might be a movie critic that it means it's okay for you to insult people for no reason.

However, you make me think of a slightly different case:

you said,

 Just to be clear, going to the store to get a loaf of bread, although one is then in public, is not what I mean by being out for public display.  One is then out for a loaf of bread, not someone shouting "look at me!" to the world, as is effectively being done when one makes a movie.  If someone chooses to be the focus of public attention, different rules apply than to those who do not make that choice.

(Bold is mine).

What is your opinion, then, of someone who is simply stepping out to the store for a loaf of bread,
but instead of dressing in conformity with the social norm,
they dress in an "aesthetically aggressive" manner....like Lady Gaga, let's say?

Many would opine that such a person is still minding their own business, and still deserves respect,
(as long as her manner of dress doesn't include a t-shirt espousing hate crimes, or anything)

but many, MANY people see such individuals as being guilty of, as you put it,

shouting "look at me!"

...and therefore consider them fair game for ridicule, or praise, or simply comment.
