Many of us in our youth took to the streets if we felt civil protest was the only way to change governments or  Legislative powers for the good of living conditions of our fellow workers or democratic rights were challenged. 
The vegan protest philosophies  however, do not fall into that category in my view and are based on core beliefs on how humans should exist today compared on how we got here over evolution. 
To be clear from the onset I am not and never will accept animal cruelty, but we have to accept the fact  the food chain exists and right down to the basic kitchen gecko chasing mosquitos to lions chasing gazelle we humans come from  carnivores and changing that will never happen, but like all beliefs be it spiritual,  political, or society changing we are entitled to have them, even live by them , but we are not entitled to force them upon others in their own homes. 
I feel invaded when people turn up wanting to convert me to their beliefs as do many, but that does not stop the right of those people holding them but forcing them by invasion is not the way to go. 
I feel deeply in  todays world animal experiments should be a thing of the past, our science should have expanded past that age, but we cannot change the way we evolved, agreed not pretty in places but to be brutally honest we as humans do much more damage to each other in daily life physically and mentally on this planet than we do to when we take to survive and maybe that’s where our own back yard would be a good place to start to clean up first.
