Woofbloodywoof, are you unaware of the things Johnson has said about gay people?
In 2010 he was supportive of gay marriage, but prior to that... not so much.
I hope his 2010 position does represent his current principles – except I don't believe he actually has any. Keep a close eye on his actual behaviour, because I suspect he'll go wherever the votes are.

Johnson’s record is not, however, without its blemishes. In January 2018, shortly after he became Foreign Secretary, a series of 20 year-old media columns resurfaced in which he wrote insultingly about “tank-topped bumboys” and attacked “Labour’s appalling agenda, encouraging the teaching of homosexuality in schools”.
Before his conversion to equal marriage, in a 2001 book, he wrote: “If gay marriage was OK – and I was uncertain on the issue – then I saw no reason in principle why a union should not be consecrated between three men, as well as two men, or indeed three men and a dog.”
