A florist or baker or photographer refuses their services and legal action follows.
I think there was one such case? Bigotry can have consequences.
TV programs will casually include gay husbands or bisexual wives if they haven't already.
So you lived under a bed for the last few decades?
Will your children be told that any type of sexual desire or encounter is good or neutral? No one likes to be forced.
The guilt is indeed unethical. This is also hypocritical: the fact that someone has same-sex attraction is evidence that it exists naturally in part of the population. You would like it to be shamed and repressed, with false arguments that it should not be natural, imposing your artificial idealistic mold of what the world should be, falsely claiming that it's "nature". Well, that's just like "Truth" that's not true, isn't it.
And the next phase is gender identity. If a boy or girl in school feels they are actually the opposite sex then they can legally use a girls' restroom even though they are clearly boys.
Since your if is wrong, the false premise, so is the conclusion, the fear mongering claim. More false "Truth" to claim that it's "not natural". You likely also promote pseudoscientific arguments claiming that biology should be turned into a social control tool, falsely dictating that chromosomes naturally direct behavior. Existing transgender people is evidence that it is false that chromosomes fully dictate human behavior, the brain is complex. That's outside of naturally occuring biological variation.
what marriage really means and has meant for thousands of years
If you really want to get into the history of marriage, it's more complex than that too and it has varied between polygamy and monogamy, slavery and purchase contracts to mutual financial agreements, sometimes even temporary marriage to accomodate prostitution. There is no evidence of a divine source behind those human contracts and claims in ancient human mythology are no more evidence.
I wish bullying other kids for being overweight, or to show your power to "persuade" them to give you money or just for upsetting other kids by disrespecting the pecking order in schools should have ended decades ago - for everybody. Teenagers would get into fistfights to show their strength or prove they were "real men."
So are you really Trump? :D
This is a situation where friendships and true, committed love boil down to 'any sex is good regardless of the mix and match number of partners." That's the end goal.
Slippery slope fallacy, conspiracy theory. False argument that it's orgies everywhere unless regulated by an authoritarian patriarch. None of your business either, actually.
