No, people like Galileo had genuine arguments and were experts in the field themselves. They were also able to have discussions without saying that people who disagreed with them were "beyond help".
Please tell me about the level of cricket that you have played, the number of cricketers that you have interviewed first-hand, how many matches you have umpired in or anything else that makes your opinion more valid than the facts and the opinions of experts who have actually done all the above.
I have answered you question, won't you offer me the same courtesy?
I am a cricket analyst myself. Analysis of the game does not require me to have played professionally, and I'm not going to admit that it does until you give some reasoning for that. I've watched almost every game of cricket played at a competitive professional level that's been shown on TV for the last couple of years, I've tracked player performances and maintained a mountain of data. Just because I'm not a pro cricketer does not make my analysis less valid.
Opinions are to be tested by the validity of the predictions flowing from them. Much more than anyone else here, I am willing to provide actual predictions and compare them with experts or bookmakers projections; I already know for a quantifiable fact tha my assessments are better than those of many so-called experts.
What you are doing is an appeal to authority.
This is what the Wiki Page on this says:
Argument from authority, also authoritative argument and appeal to authority, is a common form of argument which leads to a logical fallacy when used in argumentative reasoning.[1]
In informal reasoning, the appeal to authority is a form of argument attempting to establish a statistical syllogism.[2] The appeal to authority relies on an argument of the form:[3]
A is an authority on a particular topic
A says something about that topic
A is probably correct
Fallacious examples of using the appeal include any appeal to authority used in the context of logical reasoning, and appealing to the position of an authority or authorities to dismiss evidence,[2][4][5][6]
as authorities can come to the wrong judgments through error, bias, dishonesty, or falling prey to groupthink. Thus, the appeal to authority is not a generally reliable argument for establishing facts
