For example in the above quote. I will not agree with the first statement that drugging is rampant in the hunters. This is opinion.
I will agree with the second statement that it is known to happen. This is fact.
If you try to get me to agree that it is rampant, I might just call you a whack job and do my best to prove that there are many, many people who do not use drugs. That does not, however, mean that I don't think it happens or that it is a problem that needs to be addressed.
Some people believe that means I am sticking my head in the sand. That's okay. Because I have a tendency to think anyone who exaggerates to prove a point is really just a liar and is not to be trusted. The only real information you will get from that person is anything that supports their opinion.
