I can understand a dislike of parenthesis in the sense of it being a personal preference based on actual experience. I will admit that I was weary of them at first myself, but once I got into Lisps and particularly Schemes, I found myself liking the spartan nature of them. In a world full of complexity, it is nice to just get on with life, so to speak, when it comes to syntax, and I enjoy the regularity. F# is my favorite language, but I do hold Scheme dialects close.
