I think it was someone on this thread that wrote something that really stuck with me. It was along the lines of that because it is frowned upon for men to discuss traditionally 'effeminate' matters, the loudness and enthusiasm of some gays and women in regards to matters of style, taste and design is mistaken for actual expertise in style, taste and design.
Issues like this irretrievably become littered with generalisations. And so, fittingly, I venture some thoughts with that disclaimer.
I echo DR's thoughts, and how he tries to dichotomise 'taste' and 'expertise', in terms of dressing. I might even add a further dichotomy between 'clothes' and 'dressing'. These 4 things are at a constant interplay with each other.
Having a certain 'taste' in 'clothes' doesn't necessarily equate to having the 'expertise' to 'dress' oneself. It's not mutually exclusive, either.
A 'taste' in certain choice(s) of outfit(s) might be a indicator or orientation, but a flawed one in the majority of situations.
Bad taste in clothes doesn't discriminate genders or sexual orientations. Neither does expertise in dressing.
And, that, I think, is why it is hard to decipher each other's sexual orientation on this forum thread -- we have in common the pursuit of bettering our expertise in dressing.
