Some self-identified libertarians support government enforcement of approval toward homosexuality
Such as?
David Boaz, author of Libertarianism: A Primer. He supports [...] enforcement of homosexual "tolerance," as well as special treatment for favored minorities.
I can't find any evidence for that, but only for the opposite:
"This year, as Financial Services chairman, he’s [Barney Frank] demonstrating his interventionist tendencies [...] He wants to push all workers into government health care, to regulate corporate decisions about executive compensation, to put more obstacles in the way of free trade across national borders, to keep Wal-Mart from creating an internal bank clearinghouse to hold down its costs. Not to mention expanding anti-discrimination rules to include gay, lesbian, bisexual and transgender people. [...] would that Barney Frank come to realize that adults should also be free to spend the money they earn as they choose and to decide what contracts, with foreign businesses or local job applicants, they will enter into." - http://www.davidboaz.com/?p=309
He is far from the only one. Our self-proclaimed libertarian on the FR North Carolina Forum is all about "gay marriage"
Which implies "government enforcement of approval toward homosexuality" only in combination with "anti-discrimination" laws that are contrary to basic libertarian principles (as voiced by Boaz above).
Did you just go read his whole book?
Don't bother to answer. I don't know what your agenda is, but it is not edifying discussion, so you just go on and have a nice day. It's been fun a brief distraction from a small but very tiresome financial issue I've been addressing all day.
