All of the religions that I am aware of are pleasant enough in their own. Each one provides teachings that could make the world a better place for all humanity and all other life. All religions provide comfort for the believers.
However, all of these religions come with an associated church/synagogue/mosque/body, etc....within which are individuals who, for whatever reason (good or evil), feel that they have more wisdom and more authority than the rest of the 'flock'. While the various religious philosophies and their teachings are useful and good; this human and institutional element is almost invariably corrupt.
Therefore, on the level of institutional religions, I look at them with contempt, sadness, and rage at their purposeful corruptin of good ideas and formerly good people.
On a person to person level, most theists are amiable enough, in my opinion, although I consider their beliefs to be somewhat naive and not well thought through.
