Everyone can be wrong. Even experts. Even when they are in the majority. To anyone who believes they are absolutely right I refer them to the previous sentence. Feel free to believe you are right but don't expect everyone else to believe it as well :-)

I agree with all that.
I just expressed my views, and pointed out that the historians agree.
That is how I came by my views.

I have been told not just that I am wrong, but that I am lying, that I am fuckwit, that I am a cunt, and much else just for stating those views.

We are all free to dismiss the work, research and findings of the historians, but where else should we go to learn about History?
