The Torah uses the word “toeva” to describe the act of homosexuality. It is the strongest word of condemnation the Torah has. The fact is that even many atheists find it completely repulsive. The thought is nauseating for normal people. It’s biologically wrong.I know people who hated the chillul shabbos protests by the chareidim, calling them divisive, but were fuming that the chareidim didn’t make a bigger protest about the toeva parade. There is a midrash that says that Mitzrayim’s fate was sealed when they legally recognized homosexual marriages. I will IY”H hunt it down. I did find a bereishis Rabbah dealing with the dor hamabul that they married animals and males. The Torah is quite explicit in Parshas Veyeira that the Anshei Sdom were wicked, and part of that wickedness is their desire to “know” the guests. This was also before Mattan Torah, and was clearly understood by all to be wrong.
Bottom line- there is no way that a frum Jew can condone toeva marriages. It is no more of a right than homicide.
This is not to condemn those who have thoughts, just as thoughts of homicide without action are not a serious crime.
