If we don't keep teaching and speaking out, all truth will fade.
Are we telling our friends, even those who are deceived and hate us because they have been deceived, that the grass is actually green, fluride is a toxin and guns need to be handled safely?
A drip in the water becomes a flood when enough drips are added.
i agree, we need to keep communicating and speaking our own truth. however we should also be sure that we ourselves are not the ones being deceived. what makes you so sure you aren't the one who is deceived?
the funny thing about truth is that it depends on your viewpoint. grass IS green to the eye, unless you are colorblind, or there is never enough water. science might explain it differently, and it depends on the variety of grass. fluoride can be considered a toxin if taken in inappropriate doses or if a person is hyper sensitive. and yes, guns do need to be handled safely. they can kill people, even if by accident.
now you might believe something different. but it's not up to you or I to decide we are the only arbiters of truth. we can only be careful of knowing our own truth, and be careful to avoid bias in out thought.
for instance i believe that climate change exists. i have good reasons for believing this. someone else might tell you its a bunch of bunk. i can present evidence, and someone else can present theirs, but only time will tell if climate change is actually occurring.
truth, like religion, is a very personal thing. i don't go around telling people people to practice my religion because i feel its the only truth, even if i think their religion is nonsense. it's not only futile, it's dangerous and arrogant. people tend to be emotional about what they believe, and if they are unable to think rationally, you will never convince them the moon is not blue if they believe that it is.
we need to give people the tools and information to decide for themselves what the truth is, and trust that they will. if they are receiving false information, that is what you need to correct, not the person them-self.
