And heterosexual men have anal sex with women.
What you call a "homosexual" action is the act of having sex with a same sex partner. That is what YOU call abnormal. You deem it abnormal because it is caused by a difference in brain structure that a minority of people have.
We'll continue then to follow the same logic. A minority of people are left-handed as a result of a difference n their brain structure. This difference causes them to write with their left hands. Their dominant hand is their left.
It doesn't matter that they also use their right hands for some activities. The dominant hand is the left one. Their preference to use this hand for basic tasks is the abnormal behavior.
You choose to focus on their ability to also use their right hand. Homosexual people partake in heterosexual activities as well. You focus on one aspect of their existence: intimacies with same sex partners.
Let us then highlight the one divergent activity that left-handed people partake in. Performing acts with their left hands; having opposite brain hemisphere dominance and as a result being oppositely oriented than normal right-handed people.
As a result, further following your reasoning, left-handed people are therefore inferior and deserving of having their rights taken away.
Correct?
Incorrect. Society has considered them abnormal. Like I've been saying. You are trying to change society, not me. It is up to you to prove that they are NOT abnormal. You won't be able to, because they are. Other people who are arguing on your side of the debate have also admitted that they are abnormal.
This is completely relevant. You bring up the homosexuals participate in heterosexual activities, but heterosexuals do not participate in homosexual activities. Therefore, homosexuals activities do differ from heterosexual's activities, because heterosexuals never participate in the homosexual activities.
Left handed people perform the same tasks as right handed people, and use their right hand in addition to their left hand. Right handed people use their left hand in addition to their right hand. If these were the equivalent, then heterosexuals would participate in both homosexual, and heterosexual activities...but they don't. They aren't even close to being comparable.
In addition, they have a different brain dominance, but not a difference in brain structure, or material which composes their brains. Once again, you are wrong. Right handed, and left handed people use both sides of their brain, although one side is dominant. However, their brain structures are the same (when they are normal people....ie...not homosexual). Homosexuals in comparison, have a brain which is fundamentally different than that of normal human beings.
