I agree that abortion shouldn't be taken lightly, regardless of the trimester. Even if a fetus is aborted the day after conception, the couple might be traumatized by their ability to imagine what the fetus might have become. Technology empowers us, and power is scary.
So indeed, liberals, feminists, or progressives who take abortion as lightly as the choice between cheeses are decadent. I'm not a partisan defender of liberalism. Indeed, this article points out that liberals make fools of themselves by taking conservative arguments and rhetoric too seriously, as required by their principle of tolerance.
