""Some gay people oppose gay marriage,"

yeah.. ok.. you aroused my curiosity to read that BBC article ...

I think many who read that would discern that the main thrust is
regarding Gay people who oppose Marriage..

same as so many straight radicals and progressives
oppose the conservative concept and institution of 'marriage'...

[like me and the mrs did until we relented in our 40s
after a very long time of 'living in sin'
and married for the legal securities]

Keith - perhaps not so many gays actually oppose 'gay marriage'
as you believe is the proposition that BBC article supports.......?????
