"I think any woman seeking to have an abortion should be forced to look at pictures like these."
That's nothing more than forcing a person to understand the ramifications of their actions. If leftists insisted that everyone who wished to have sexual intercourse be forced to look at pictures of babies, I would support that as well. (Yes, I know I reversed your analogy, it doesn't work the other way.)
Gays kissing? Maybe force everyone who wished to have gay relations to read up on the pain of AIDS? Yea, there's another good idea.
I'll take it a step further. Maybe we should include pictures of bad car wrecks in Driver's Ed?
And lastly, as far as the mobile billboards, I don't think everyone should have to see that. Many people however, do need to see it, and even if there's only a slight possibility of saving a single child, that concern must take precendence over all else. My discomfort is of little importance in comparison.
"Your analogies are apples and oranges, if they're even both fruit."
You are missing the point. The point is WHO DECIDES what people have to look at? You don't have any more right to force people to look at something they don't want to than they have to force you to look at something you don't want to. This is America and thats how freedom works. At least thats how it is supposed to work.
