You love it, don't you. Twist it turn it, until you like it.
Whoever is being kissed by whoever is not the issue. I don't give a sh@t about who is kissing who. Woman, man, gay man, lesbian, trans, pan, black, white, Muslim, Christian, etc, etc.
The issue, in these days of desired equality, is the polar opposite reactions to a kiss, depending on who does what.
Kissing someone, partners excluded, is either wrong or it isn't. Which ever stance the public, media or keyboard warriors want to take us fine by me but keep to that stance regardless of gender, race, religion, sexuality, sexual identity........etc.
