yes he's a signatory to that letter. he's not as loud mouthed as hanson, but he's in that bunch all the way. in any case, he himself doesn't have any issues with using his pre or post Islam names interchangeably his own employer lists him as Timothy Winter, they'd never do that if he voiced an objection against it https://www.divinity.cam.ac.uk/directory/timothy-winter he even authors papers with his pre Islamic name https://scholar.google.com/scholar_...AGBfm0H0rpaYlg4a_OHyE6mx3kkwdbf9g&oi=scholarr https://www.bloomsbury.com/us/author/timothy-winter/ all that said, i would reemphasize that even if he did propagate his post Islamic name, it'd still be warranted to call him with his former name
i searched it a while ago but i only found his name mentioned in passing, nothing really concrete for the usage of his pre-Islam name to be warranted
Sh abu Hasan and this forum as a whole seem to have some strong beliefs regarding him, considering he is mostly called by his pre-Islam name. Is there a reason for this? I know very little regarding him but I do know that he is accepted in most other Sunni circles. I've not read any of his works either but a brief scroll on his wikipedia showed some seemingly beneficial books and topics - the page also mentions his signing of a seemingly perennial message to christians. Is this the reason?
