I think some protest tactics like blocking walkways hurt more than help progressive causes.

77. You're kidding, right? Have you ever publically protested anything yourself?

The whole point is to inconvenience people and make them recognize there is a problem -- a big, big, problem.

If civil disobedience is called for, the whole point is to be really truly disruptive, and knowingly take the risk of being beaten and/or jailed. Make sure the cameras are there, so the whole world is your witness. What do you think Martin Luther King was doing? He took this technique from Mahatma Gandhi himself.

How far do you think either of those men would have gotten by inviting their opponents in for tea and crumpets?

Risks to people with disabilities? A well-planned protest action will have contingency plans for the injured, and by extension, the disabled.

Blocking traffic? See first two paragraphs above.

Looting? I beg your pardon. Have you ever heard of COINTELPRO? A well-planned protest action will have contingency plans for trolls and disruptors too, and will give them the boot as soon as they are identified. No violence against property or people in civil disobedience: somebody starts advocating that, they aren't with you they are against you.
