Really depends on conditions. Many “bike lanes” have unsafe road hazards, glass, are immediately in the door zone of parked cars, etc. Getting doored is one of the most common causes of cyclists being sent to the hospital with major injuries.
A well laid out, well maintained bike lane is a better alternative to taking the lane. However, in the cases where the bike lane is hazardous it’s always better to take the lane than to risk getting injured in an unsafe bike lane.
The point is that you shouldn’t base your decisions on whether or not you can say you are “vegan”. You should base your decisions on your own sense of ethics.
Whether or not beekeeping harms bees is a matter of debate. If a person believes honey is ethical, that’s their decision. Who gives a fuck if it meet someone else’s standard for a particular label?
