I say you are using this to attack Christianity because you are using it to attack Christianity. Would you even deny that you have a certain antipathy towards Christianity? I do not think it is a well kept secret that many do.
Just... yeah, this is annoying. Christianity isn't a blanket term anymore, friend, and it's one of the reasons that "Christianity" (note the scare quotes) does catch a lot of flak. A person can have quite a bit of antipathy towards the folks that are abusing the religion they claim to follow in order to exercise (unfounded, harmful) prejudice without having some blanket malaise towards that religion and all its practitioners.
I don't think anyone here is actually "attacking" Christianity qua Christianity -- pointing out certain inconsistencies involved with the religion is far from an attack -- but they is some understandable hostility towards the people who are using the title Christian as an excuse to pander hate. There's no assault on Christians here, really. There's assaults on heretics insulting the name and teachings of Christ and calling it Christianity. There'd be a lot less of that sort of assault if the rest of Christianity would start joining in (a little more visibly, anyway) on piling onto these people dragging Jesus's legacy through the mud.
Though I may be taking that last sentence or two a bit far. I'll admit I get a little riled up about that.
You seem pretty confident as to which people are which despite claiming Christianity is not a blanket term anymore. I'll toss one more verse your way as a manner of describing to you why I do not have a lot of faith in your interpretation of the matter.
1 Tim 6:3-5
3 If any man teach otherwise, and consent not to wholesome words , even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness;
4 He is proud, knowing nothing, but doting about questions and strifes of words , whereof cometh envy, strife, railings, evil surmisings,
5 Perverse disputings of men of corrupt minds, and destitute of the truth, supposing that gain is godliness: from such withdraw thyself.
KJV
And
2 Tim 3:2-7
2 For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy,
3 Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good,
4 Traitors, heady, highminded, lovers of pleasures more than lovers of God;
5 Having a form of godliness, but denying the power thereof: from such turn away.
6 For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts,
7 Ever learning , and never able to come to the knowledge of the truth.
KJV
Christianity is not a complex concept. We are all imperfect. Imperfection leads to destruction. We cannot do anything for ourselves in this matter, but Christ can. The question is, do you believe in imperfection? If so, WHAT is imperfection? What is sin?
You claim a lot of confusion exists, but it does not in fact exist anywhere except in the minds of those who wish to be confused. It is not a mystery why homosexuality is not wholesome. Questions and suspicions about it abound in almost all cultures. "Two Spirits" in native American culture were simultaneously revered and yet feared for their unusual state of being one gender but acting like the other. I know of one story where the "Two Spirit" native American was at first respected as a good leader, but then later killed because things went bad and they suspected them of bringing bad spirits on the people.
It should be obvious here what the real underlying issue is -- human beings are wired to have heterosexual attraction AND to be at least mildly repulsed by homosexuality. THAT is the issue. THAT is what you and others of your mindset seem to want to avoid addressing at all costs.
