There is absolutely no connection between one's respect for those of the Jewish faith and also seeing that the establishment of the modern state called Israel was a huge mistake for everyone, especially Jewish people.
Actually, there is. Since most of 'those of the Jewish faith' see it very differently, your POV that 'establishing Israel was a huge mistake for .... Jewish people', carries with it the assumption that you know better than the vast majority of Jewish people, what is good/not good for them.
At its best, such a view is 'paternalistic': it absolutely is NOT 'respectful' in any usual sense of the word.
Well, perhaps you are used to telling your friends what's good for them - and they are used to listening to you. It hardly seems worth the effort, particularly when you endow your personal opinion with 'fact' status and give no explication whatsoever.
