Driving is more than stepping on the gas and turning the wheel.Things happen.... All the time. Some are not benign. Does that justify imposing your brand of conservatism on others. Living is the sole cause of dying. Everything has some risk and is perceived differently by each. What you describe is an unlucky situation arising directly from a clot and an infraction by one of the "safe" drivers participating. If you had to brake that hard the turning driver didnt give proper notice and the reaction stackup of the tight clot made it a bad situation. A seven foot long motocycle is not going to affect the distance you have to stop to any appreciable extent - unless he just clamps them on and stops faster than you can. Im surprised the rider didnt chose to brake easy and get out of the potential squeeze by moving over - experienced motorcyclists are very atuned to this option when they encounter a need for a quick stop in traffic. Even tho going faster than you the MC stopped fine. His tires werent smoking but yours were and the bike behind was having trouble. Im not sure whether you over reacted or not, but the MC didnt cause this - the clot did. If he hadnt been there yould still have had a hard stop. Yet you are quick to cast blame based on what ifs for the people who try to move thru the clot. What about the person who started it by overtaking the leader and sitting on his bumper and not passing? No complications for him; clear lane ahead just check for oncoming traffic. Defensive? Afraid to pass? An under the radar traffic hazard? --Catalyst for problems with traffic flow yet free of all responsibility for such. Far too often the defensive driver causes problems, especially when they think they should impose their concept of safety on everyone.

Whether on a bike or in a car, if you pass at a high rate of speed (those speed limit signs are there for a reason) then cut me off and slam on your brakes YOU are creating the situation. What you call a "clot" is normally a line of traffic moving at a sane speed for the conditions, whether it be snow, a dumptruck, or turning traffic. YOU create the hazzard, with your need to be in front. A safe space becomes unsafe when you pass unsafely, then pull in and slow down.
I encounter guys like you on a regular basis; traveling along in your own little bubble blaming everyone else when the road isn't clear. I've learned to leave a little more space in front of me to account for your errors.
