Since you only have 4 posts, I will remain open to your question.
When you have someone make reference to a convicted felon and continue harping on personal things that happened over three years old, that's low class. When you make other references to unproven facts that were meant to be harmful to Tiger's reputation, then that is low class. When you have another individual totally agree with the original post, and that individual has a history of posting only negative comments against Tiger or his fans, then that is very low class when they take place on Tiger's web site.
If you still question what " low class" means, then please, you need to get an education.
