This is a discussion is it not?
Yes, and discussions are usually give and take. You state something, someone else responds, you build upon that. If there are disagreements, you debate: you advocate your side, the other person advocates theirs, and you both try to come to an understanding.
I'm just stating my own opinions in my own words. What kind of statement is it to say 'He said it first so you shouldn't say anything at all?'
I didn't say that. What I said was your argument has already been stated earlier and, I believe, adequately addressed.
What's the point of discussion with this kind of reaction?
I was just pointing out that things were going in circles. The point of debate is generally to move forward, to better understand and improve upon our beliefs. Repeating what has already been said isn't really useful to that end.
As for my reaction in general, I just think that the idea that incest is unethical because of
potential genetic resulting from
potential childbirth doesn't make sense and shames good people who really have nothing to be ashamed of. People suffer unnecessarily (often severely) because of societal attitudes on incest and I think our attitudes on it are something we should be rethinking, considering the illogical foundation for them.
And yes there are over seven billion people in the world, what does that have to do with anything, seven is 'more than three billion right?'
It was just something that sounded weird, so I pointed it out. I don't see why you're questioning it, it
is kind of weird to put it that way, and it was really just an afterthought to the meat of what I said. I would have just conceded it and moved on, it shouldn't be that important.
At no point have I used any emotionally charged language, insulted you, or done anything other than address the topic at hand. My motivation here is (I thought pretty clearly) not to personally attack you, rather it is to make a convincing argument about why I think what you said doesn't make sense and is ultimately harmful and why I think my position makes more sense.
Regardless of what has been said or what numbers you do or do not have, I'm still against it.
You can believe what you want, but the point of a debate is for everyone to better understand the varying positions on a topic, including your own, and progress forward. If someone adequately addresses your argument with a counter-argument, generally you either concede that they're right (either in full or just in part) or you point out why they're wrong. If you make an argument that 2 + 2 equals 5 and someone points out that this is incorrect, you can say "well I believe it anyway" and no one can stop you, but that's kind of missing the point of having a debate in the first place.
Also, my argument barely touched on numbers at all, and I was even willing to concede that the numbers I gave just came from my memory and thus weren't really solid enough to make a solid argument on. Most of what I said was just logic and rhetoric.
