I really do feel sorry for people who refuse to believe some things, and who poo-poo everything. Some even doubt science fact that is spoken by physicists and scientists. No open-mindedness at all. Bit sad really. I'd hate to live like that.
I don't think anything is impossible but believe that "extraordinary claims require extraordinary evidence" and the strongest evidence for the Bold Street time slips appears to be a lady called Julie recently claiming to be the subject of one of the stories that has been doing the rounds on the internet for a couple of decades. We do not so much as have the full name of anyone else from the various stories, nor a first-hand account from any of them.
It looks like Julie claims to have experienced several time slips. I am willing to accept that it is possible that she is genuinely experiencing a real phenomenon, however, I think that either (1) she is making it up, or (2) she believes the stories to be true but is experiencing hallucinations or similar are far more likely explanations. We know that people frequently makes things up and we know that it is quite common for people experience hallucinations otherwise mistaken.
I will not rule out the possibility of time slips or apparent time-slips but I'm very happy to refuse to believe in fantastic claims that have extremely scant evidence.
A bit of a detour but, as many will know, Donald Trump recently claimed in. Presidential debate that Haitan immigrants in Springfield, Ohio are eating people's pet cats and dogs. This has led to various threats of violence.
We know that the origin of this story was a Facebook post, where a woman claimed she had heard it from a neighbor, who heard it from her daughters' friend, whose cat was eaten. The neighbor has since clarified that she did not hear it from her daughter’s friend and that it was not her cat, but that it was just a rumor she had heard from an acquaintance and she does not believe it to be true. Masses of journalists have tried to uncover a source for the story but so far, the best evidence is that a woman heard a rumor, which she does not believe, from an acquaintance.
Nonetheless, 52% of likely Trump voters believe the claim to be true - which would be in the region of 40 million people.
I don't think it's healthy to have quite so little skepticism and such an absence of skepticism is both very common and potentially very harmful.
