If the US overnight became a right wing evangelical theocracy, gays absolutely would be executed (eventually, as that's where unchecked dehumanisation always leads) but in true American fashion by something needlessly complex like a Rube Goldberg death machine rather than a simple hanging.
Do you know what most evangelical Christians believe in? ExtremeRepublican, who is a pretty good median representation of the American Evangelical Christian, doesn’t even support overturning
Lawrence, let alone
executing gay people.
For instance, the
most one could argue is that Evangelical Christians in the USA have similar views on homosexuals/homosexuality than the country as whole had prior to 1969. Can you find a single example of someone being executed for being gay in the U.S.A prior to 1969?
