I am of the opinion some individuals feel that there vote or voice doesn’t matter in the end. We are after all just constituents, and taxpayers who vote everyday with our dollars. Each day we wake up is a blessing and is an exercise in free will, you can attain goods and services with your given level of money, thereby choosing what you deem a priority in life.
I know for some religious groups, getting involved politically goes against their teaching, which also inadvertently allows good or evil to prevail.
There isn’t a good excuse for not getting involved; complaining about the system you do not wish to participate in is a waste of citizenship and hypocritical. Just my two cents.
