Unless pro-lifers at UVic are chasing down pro-choicers, following them home, making obnoxious phone calls, or spamming their in-boxes, only a liar or an ignoramus could accuse them of harassment. Simply because you've seen a poster you don't like doesn't mean you've been harassed; what an astonishingly privileged world these people live in, when they believe their rights are being violated if they see or hear something with which they disagree!
Pro-choicers, listen carefully: human beings have rights, and we won't stop defending those rights because it makes you upset. If you don't like what we have to say, suck it up and oppose us in the realm of ideas; invite pro-choice speakers, put up posters, and present your argument intelligently.
I love their panache. It makes me think of a personal theme song of mine:
Eye of the Tiger
It's the thrill of the fight
rising up to the challenge of our rival.
Oh yeah, baby! Eye of the Tiger! :)
