sephardim

Question

In the article written by J.M. you objected to a few of the things written there. I personally feel that there were a few more things that need to be objected to. Please correct me if i'm wrong. 1)There's nothing wrong with a sephardi wearing a black hat.It is not an ashkenazi thing. It is a modern day custom.(I know Rav Abadi wears a black hat.) 2)The article seemed to imply that there's something wrong with a sephardi shul putting up an ashkenazi speaker. Is the sephardi torah different then the ashkenazi torah?! If the ashkenazi knows torah then what's the problem if he speaks in your shul? Do you have a problem with ashkenazim using this website to as a way of getting psakim from a sephardi posek? Do you have a problem that Rav Abadi is the rav of an ashkenazi shul? Rav Shach zt'l said that his dream was that ashkenzim should come to a sephardi rebbe to learn torah. He knew that torah is torah and that people from 2 different backgrounds can learn from each other. Please correct me if anything i wrote is untrue. Thank you very much for all the work you do.
