At the same time, there are people who revere them as spiritual vessels, such as jains. Sometimes I would think they would be even more outraged than they are when a guy like me comes along to wipe out some ants.
It has nothing to do with how people view them, spiritual vessels or not that is NOT their point. The fact comes up that if you are given the power or ability you would do the same for humans because how would you draw the line? You see ants as insignificant, why would you think anything else is significant? But it doesn't stop there. It means you have no respect for the chain or cycle of life itself.
Which means you don't care about what sort of service they provide nor care to wonder if they are providing any service to the web of life. So by taking a huge **** on ants means you take a huge **** on life itself. So they get annoyed that they should respect you for your ignorance.
It is similar people with your mind set which lead to the entire planet being **** on without any care for it's future or what sort of damage is being caused.
"Should we cut down a hundred thousand acres of forest?"
"Sure it's not like anything important is using it and we need it so why not?"
"What about all the wild life using it?"
"**** em, they are just ants and bugs anyways.. they aren't important for anything."
