Sexual intolerance on a political level is perhaps the best thing for society. This is not an attack on the gay lifestyle. This is an attack on the attitude that sexual tolerance will make life any easier for anyone, gay or straight. Political intervention will accomplish nothing by endorsing complete sexual freedom. Intolerance regarding race and gender is insulting because a person's race or gender does not dictate his or her actions.
Intolerance regarding morality is very different.
People must be able to discriminate when questions of morality arise. This does not justify attacking a gay man or torching a gay bar on the basis of this discrimination. But when a government tells the people that one morality must be tolerated over another, there is an injustice. One group will find its moral beliefs disregarded by the Government. Male-female relationships will always be preferred to homosexual ones.
