Another false logic argument. You left out a myriad of various other reasons and again you are guilty of the false equivalency faux pas. Its pretty simple. You find something that relates to carrying a living person in your body and being responsible for that person during and afterwards. Can you do that?
If a free society allows you an opinion on one topic that is not related or not directly related to your own experience, than it allows it on all. Don't me mad that I am not taking your "shut up" bullshit. It's a topic of public policy and I can have my opinion on it, and If enough of us have the same opinion on it we can force it no matter how much you whine about it, even if it takes getting a constitutional amendment.
"Just shut up" is intellectually dishonest, lazy, and shows that the current crop of progessive morons such as yourself cannot argue anything on merits, just argue that the other opinion shouldn't exist "just because"
