Straight after that last comment you cite, I pinged all other moderators to take over the moderation of the question. I don't want you to think that this question is being moderated unilaterally simply because I am the only person who left the comments. There are multiple eyes on it.

That said, the specific claims you quoted are about two different cases. It's fine to ask whether they happened, even both in the same question, IMO. Note though that whatever their veracity, they refer to specific situations which are not meant to be representative of a larger phenomenon.

  The twitter chain ignores this and speculates this is a more general phenomenon. It does not state this as a fact, IMO, nor I see any evidence that people believe this in large numbers. You don't provide any verbatim citation of this, either. Yet, your question is about this more general phenomenon and not the two claims above. As such, it's up to you to prove notability of the general claim, if you want to ask about that.

To this, add the multiple complaints of other users that point out more problems about the claim (i.e. that we are not assessing whether Republicans refuse to believe facts, but partisan interpretations thereof).

Finally, the question is dangerously close to be a question about personal beliefs. It's not so that I would close it on this basis, but certainly that counts a little bit if thinking about reopening.

Straight after that last comment you cite ("Find a specific, factual claim..."), I pinged all other moderators to take over the moderation of the question. I don't want you to think that this question is being moderated unilaterally simply because I am the only person who left the comments. There are multiple eyes on it.

In any case here is an extended explanation of the closure. The specific claims you quoted are about two different cases, G.W. Bush and Romney. It's fine to ask whether the episodes claimed happened, even in the same question.

On the other hand these two claims refer to specific situations which are not meant to be representative of a larger phenomenon. The twitter chain ignores this and speculates this is a more general phenomenon. It does not state this as a fact, IMO, nor I see any evidence that people believe this in large numbers.

If I may add many of these claims are also about the future, i.e. whether a policy will have an effect.

Finally, the question is dangerously close to be a question about personal beliefs. It's not so that I would close it on this basis, but certainly that counts a little bit if thinking about reopening.

Given the above, I don't feel comfortable reopening at the present time.
