Indeed it's hard. That's the realization it takes to persist despite the adversity in those who don't have the same care for truth, and choose to remain undriven by truth, not learning, not seeking to understand more. Either you persist or give up, and what would giving up do but let things be as they are and not change for the better? It's going to take a lot of people to care for truth if we want to actually get some real and lasting positive change.
