SJS, you’re halachic disagreement whether it is stealing or not, is just that. A disagreement whether it is or is not considered stealing underthe eyes of halacha. Honestly, mw13 is more compelling. But either way, NO ONE condones stealing — assuming something is stealing.
AND even IF it IS stealing, stealing’s halachic recourse is repayment of double (or sometimes more) of the stolen amount. Toeiva (homosexuality) is a capital offense that carries a death sentence. (Even for non-Jews under halacha.) Incomparable. That is far worse any way you look at it. So yes, the latter is very much worth railing so hard against, even more so than the original.
