Where are the old and New Testament scriptures on homosexuality?

In addition to the verses that some Christians use to persecute gays and lesbians, there is also one verse that seems to support gay people. Genesis 2:18, which says:

וַיֹּאמֶר ה׳ אֱלֹוקים, לֹא-טוֹב הֱיוֹת הָאָדָם לְבַדּוֹ; אֶעֱשֶׂה-לּוֹ עֵזֶר, ×›Ö¼Ö°×?ֶגְדּוֹ׃

And the ETERNAL G-d said: 'It is not good that the man should be alone; I will make him a helper for him.

The Hebrew Word for Helper in this verse is ezer (עזר) which is masculine. Now it is true that masculine Hebrew nouns can also be used generically to include the feminine, but if this "helper" was only supposed to be a woman, we would expect the Word ozeret (עוזרת). We can conclude that this verse could apply to male helpers or female helpers.
