Oh, I don't mind indentation per se... but in C++, the worse that happens with a misplaced tab is that the code is a little harder to parse visually. In Python, a misplaced tab can cause logic errors that are a real gnoll to track down and will usually not trigger an interpreter error... Misplaced curly braces are the bane of my existence when writing C++, but at least they tend to throw compiler errors that sometimes give me an idea of where to start for fixing the problem and when I got a few lessons in Python, the whitespace sensitivity got me nostalgic for misplaced curly braces.
And don't get me started on Python source code that uses spaces in multiples of 4 instead of tabs for indentation or which mix tabs and spaces in their indentation... making sure every line of a code block has exactly 4 leading tabs is hard enough... making sure they all have exactly 16 leading spaces is a nightmare... And hey, it's probably possible to write a bash script that can automatically fix indentation in a .cpp file, but you kind of need to know what the program is supposed to do to have any chance of identifying when a line is indented by the wrong amount. Granted, if I knew how to make my console screen reader speak whitespace when reading character-by-character(and thus could tell tabs and spaces apart) or how to toggle between a less verbose "prose" reading style and a more verbose "code" reading style where reading line-by-line speaks characters that are normally unspoken, it would probably alleviate some of my dislike of whitespace sensitivity.
