I do, mostly because of all the things you've listed above. There are too many variables to make abortion completely illegal. Also, there's a lot of suffering in this world and if a child would be born with horrendous disabilities...not even thinking of myself as a possible parent, why would I do that to another human being if there is an option to stop that suffering?

However, I recognize there's definitely a moral gray area and I am flabbergasted at the "shout your abortion" trend.
