Hoax?
I have trouble believing that someone so upset at the idea would say I’m arranging a protest or call it an “anti-gay” group instead of traditional marriage group.
The two occasions I’ve received such invites, I just said no or heck no. I can imagine someone sending back a traditional marriage pamphlet or Bible verse, but not anything this stereotypically “homophobe”.
Once, I had to explain to the woman how it was blasphemy, so no, we aren’t coming, but this conversation was politely done as possible. I wouldn’t have interrupted the event itself.
For some people, the response would be to tear it up or ignore it. Few would seriously think or even threaten to PROTEST and disrupt the event.
