Creating road blocks in the middle of a highway, is not a protest.
Trespassing on private property is not a protest. An open door doesn't give you the right to disrupt what's inside.
If it did, then what's stopping me from going into planned parenthood to protest partial birth abortions?
The law, that's what. These protesters are not normal people, they are funded by George Soros, Jesse Jackson, and Bill Ayers. Same groups, different names. 99%ers, BLM, etc. Their objective is to cause chaos by breaking the law.
