I may not be an expert but my understanding of how crypto works is fine. What you mistake for an ignorant statement was actually a personal observation, clearly explained in the previous sentence.

My observation was that : After the fork, I noticed a sharp decline in my daily earnings. I speculated that this was probably due to the difficulty being disproportionate to the short time after the fork and the hashrate being produce on the hardware mining on the new algo.

After most forks the difficulty should be very low and increase slowly over time as more and more hash hits the new algo.

So before you start insulting my intelligence perhaps you should read more carefully and understand what the person is saying no?
