Gospel should be preached properly. Not by homosexual pastors, divorced pastors or female pastors.
Jesus allowed a foreign woman, who had had 5 husbands, and a woman who had had 7 demons cast out of her to preach his word.
Jesus called a tax collector, political zealot and men who would deny and betray him to be his disciples, preach the Gospel, drive out demons and see, and do, miracles. He didn't wait for people to become perfect before he chose, called and used them.
Women preach the same Gospel as men do.
And if you are saying that if someone's partner has had an affair, walked out on them and later filed for divorce - and this prevents and excludes their divorced but innocent ex partner of preaching the Gospel; you're wrong.
Not sure what you mean by that no rational argument can be made against them.
I mean that there comes a point in these debates/arguments when people are asked why God allows it to happen/why he is calling women today etc, and the only answer they seem able to give is, "well he allows homosexuality/sin etc".
Its simply against the Bible.
As God called, worked and spoke through a female judge, female prophets, queens and servant girls; as Jesus allowed women to follow him, speak for him and be his witnesses, as the early church had female workers, apostles, prophetesses, teachers etc - it's clearly not against the Bible.
If God didn't want this to happen today, he wouldn't call women to do this and men to agree, train and anoint them. He wouldn't speak to them through his word, he wouldn't go against his word.
My guess is that you're thinking, "he doesn't".
All that means is that you won't accept that your reading of Scripture is wrong. You can't be wrong, neither, obviously, can God, so it's much easier to dismiss, and write off, thousands of Christian women as being mistaken, deluded, disobedient feminists.
All over the church God is raising up women to serve him and men are agreeing, training, ordaining and ministering alongside them. You may not like or accept it; doesn't mean it's not happening.
