Each golfer has a different viewpoint, seeks different things form not just his own game but the course as well. Perhaps the tendency of private courses brings out the Gentlemen in us, so criticism is not seen as the way to repay the courtesy of playing their courses.
Then there is Criticism against Cnstructive Criticism or ones opinion of the course laid out in the pros & cons of said course.
As you well know each course by its very nature (and man made effort) are different, from the weather conditions, landscape, location, and not forgetting purpose of the course. (To many courses are now trying to be what they are not i.e. Championship Courses and should settle for what they are, just great members courses open to those that want to share that experience).
Criticism if that is the right word, should be aimed at the new ‘Young Pretenders’ to TOC, North Berwick, etc. etc because they are just out and out commercial/industrial units charging more that they are worth in the belief that they are or may become Championship Courses. Criticise the intended purpose but not the course (no matter how we each feel about it), it will please some, while others dislike it for various reasons. As you know, my pet hate is to have a well kept manicured course out in a wilderness with the surrounding land not reflecting any of the courses features.
Criticise the purpose of the course, rather than the course itself and remember the old saying ‘One man’s meat is another’s poison’.
