It certainly comes off as you were threatening me for telling you what to do but regardless of who you are threatening to punch for telling you what to do it is uncalled for.
Take my advice for what you will. I am simply offering you a more appropriate place to post your daughters videos so you do come off as one of 'those parents' who is more interested in their child's status in the cheer world than just a proud parent because whether you see it or not there is a line that can be crossed.
For what it is worth, though I may not like being told what to do, a threat of punching someone IMO is not an acceptable way to say I choose not to do what I am told.
