The scriptures are fine , and the basic scriptural truths about God , Jesus and his return are found in most religions. It is the special understanding of things that the WT has , that is illogical.
Christ is supposed to have returned invisibly in 1914., that is 108 years ago! For me the time lapse is no longer credible, seeing that Jesus said “ this generation “ . The attempt to explain this by overlapping generations, still being that generation, are pure invention.
I could go on , with their u turns and abandoned beliefs , all presented as divine revelation but I am sure others will do so
