Explosive is not a stong enough word.
It is devastating to their "world view" that it is a orientation which they have no control.
Provable, experimentally repeatable results which have sexual behavior as mutable back to normal conduct means there is no reason to have homosexual marriages. There is 100% reason to prohibit homosexuals from adoption or even child custody.
Of course there are countles empiricle studies which sexual behavior reverting back from homosexual to normal based on studies of the sexual conduct of long term prisoners.
ALL the studies which were supposed to point to a fictional homosexual gene have be unrepeatable and put into disrepute.
Should such studies continue to build evidence, the homosexual loby will just change their tactic and say it is just a matter of choice. They will then compare themselves to the abortion movement. The homosexual lobby will not give up their fetish without a fight.
Homosexuality is just like ADD and Depression, as in we choose to not pay attention and we choose to not be happy, yet doctors try to say that we are born that way.
I was diagnosed with both ADD and depression and had to take medication to "help me" but it didn't work and in some cases the medication hurt me, so I choose to pay attention in school and be happy and it worked.
