As a beginner I felt unwelcome. My first question here was put on hold on the grounds that "requests for trivia or basic historical facts are off-topic". My question is not asking about trivia. It's questioning an assertion and even tries to provide some evidence to back it up. I've shown research effort, I explained clearly what I'm looking for, and I have provided some clues that a statement that has been accepted for a long time might be wrong. It's true that a good answer would need research effort as well, but that's what we are here for. So I was led to believe.
Then again, a biased answer which showed only one's "opinion", no research effort at all, and provided no links sources, or references, was not criticezed at all and was even upvoted. Good answers provide links and references. Saying "I believe that.." or "I'm sure there are other..." is not what SE recommends.
Beginners should be welcome on any SE site, especially when they are serious enthusiasts. You forget that you're still on Beta and that you need retention. Nobody ever said "welcome to History Stack Exchange, Centaurus". Good manners count.
I expect the moderators and those who have been here long will consider these points.
