Between blotch and blok

And yet you're in favour of being closety around homophobes because they'll get offended and social support is on their side? You think it's up to LGB people to avoid offending homophobes?

I think you're comparing apples and oranges again. In terms of social norms versus aberrant phobias, homophobia is moving more and more clearly now into the phobia camp for most of society. It's no longer legally sanctioned, for example. Breastfeeding, equally obviously, isn't by any means so clear-cut. You think it should be entirely acceptable; I think that whether or not it should be acceptable is immaterial, because it self-evidently isn't and for the foreseeable future is never going to be. And in that atmosphere of deeply grey areas, I think it's by far wisest to put the politics on the back burner and do what you can to avoid constant stress and confrontation. Particularly if you've got a baby's wellbeing to think about.

you have a right to offend anyone

No, I don't have a right to offend. I do, however, have a right to express my opinions without being insulted, accused of deviance and assumed to be a bigot.
