I noticed this post the other day - but you made me re read all the posts.
I cant actually see anything that seems to be rude or offensive in those posts.
None of them have said there is anything wrong with the OP for not liking the flashing lights.
But as you have noted, there are only limited solutions to the problem, coupled with the fact the OP didn't seem to know what makes the lights flash. It is actually quite difficult to explain this to someone without sounding a little patronizing to others perhaps....
