Update:
Apparently ANTIFA did make an appearance and attempted to intimidate and belittle the marchers. According to one source, the police did not make any effort to keep them away. They did make an effort to make sure that the march did not pass the Morgentaler abortuarium however.
Looking for video of any of that today.
