This cyclists versus drivers thing go both ways. There are azzhole cyclists out there who would blow by stop signs/red lights without even stopping.
Is azzhole warranted? As long as you're aware of your surroundings there's nothing wrong with blowing a stop sign or red light in my book and the drivers in my lane should appreciate that as it takes a while to build that momentum up to 20mph again so it works in their advantage too.
I will never understand aggression towards cyclists, purely ignorant.
