If you don’t like it, don’t read it. It’s as simple as that.
And in any case, I can cite any number of rabbonim, Orthodox, Conservative and Progressive, not to mention Jewish scholars of Biblical Studies, whose commentaries trouble the straightforward reading of both the Vaikra verses referring to homosexual relationships.
Moreover, even some of those who agree with the straightforward reading (minus the “put to death” part, it’s been millennia since our tradition has evolved to understand the Torah as more sophisticated than “put everyone you don’t like to death”) have said that it is better to welcome gay couples to synagogue than to alienate your fellow Jews on a matter that isn’t even your business.
And if you’re a Christian, you shouldn’t be tossing Torah quotes around like that, your own founder has repeatedly said the new laws he brought you supersede the old law, so maybe like, Vayikra’s kinda irrelevant to you. I’m sure you can find plenty of crude homophobia to cite from the writings of the Apostles and Shaul HaTarsi, nu?
