Supporting the ideals (lower taxes, America first, border security, etc) of someone, doesn't mean you're supporting his personal life. The two are separate. Hillary Clinton was the other choice and not only is her personal life just as bad, if not worse, but her pubic life and illegal activities don 't get support from me. I support most of Trump's political endeavors and ideals.
Now, back to the subject at hand. Homosexuality, just as adultery and divorce, is wrong and I do speak out against it. God tells us that the only exception for divorce is if your husband/wife commits adultery. But even then, it's frowned upon.
