So, my take.....yes, kinda. In your circumstances, I would wear something to catch an accident, because the cleanup will be so much easier, but I would still try to make it to the bathroom at least in public places, to be kind to those around you. At home, it would be perfectly understandable to let go instead of fighting to the point of pain to make the restroom, but in public, being kind to bystanders ought to be a consideration, plus cleanup on a BM in a diaper is an order of magnitude more difficult in a public bathroom than it is in your own. But if my colon were acting flaky like that, nothing could convince me not to wear a diaper, just in case.
Shaving there makes cleanup a ton easier. I recommend Magic red and white can shaving powder, and wrote about it pretty extensively here:

I'm sorry you're going through this, and hope you get it under control quickly.
