Me: I think money printing by the Fed will cause inflation if they continue like this.
Not as long as interest rates remain at or near zero. The economy is in a weird place right now. Normally, people who have money but don't want to spend it immediately will lend it in order to receive interest. However, with interest rates so low, people who would normally be lending money - including banks - have little incentive to do so. Money is ending up under Apple Computer's proverbial mattress instead of being spent on things. Making things worse is that the Fed's normal method of "printing" money - giving people cash in exchange for short-term Treasury bills (which are currently paying near-zero interest) - only puts money in the hands of people who aren't going to be spending or lending their cash, and money not spent doesn't cause inflation. (If they wanted to spend or lend the money, they would have sold their T-bills to someone by now.)
This is an example of refuting my argument by actually arguing about it instead of discrediting me because I am not an economist.
My problem is when instead of your answer above you write "are you an economist? have you investigated this?" with the obvious objective of coming after my answer with an "ok, so your premise is false because you don't know what you are talking about".
Especially in the comments of political articles or about economic issues I find myself arguing with people who question my authority about a topic rather than refute my arguments.

Examples may be:
1:
Me: I think money printing by the Fed will cause inflation if they continue like this.
Random commenter: Are you an economist?
Me: I am not, but it's not relevant.
Random commenter: Ok, so you are clueless.
2:
Me: The current strategy to fight terror is not working because ISIS is growing.
Random commenter: What would you do to stop terrorism?
Me: I have an idea of what I would do, but it's not relevant because I'm not an expert, but do you think the current strategy is working?
Random commenter: So you don't know what you are talking about.

It is not about my opinions above, or even if I am right or not, I would gladly change my opinion after a debate, but I think that I am being disqualified unfairly.
If I am right, how should I answer or continue these conversations?
