DreamerCM, I have read your posts, and I understand where you are coming from.
You state you will not climb over people. Instead you will sit down next to them, in the middle of the row.. No one should go and kick your son, or any kid for that matter on purpose.. In fact, the people who would have sat in the middle of the row before you should suffer the hurting feet...
You jump on people here for "acting violent" by kicking someone who is rude and making things difficult for others to be seated.. Then you say if someone kicked your son more than kicking would be happening.. Sounds like you are issuing a threat of violence yourself.. In defending your son, sure.. But when you sit in the middle of the row, and people are trying to fill in ALL AVAILABLE SEATS.. then, sorry, but you should expect getting kicked or getting your toes stepped on... Was it intentional or an accident? Who knows.. But the people who fail to listen to the CMs repeated instructions to move all the way down to the end of the aisle only bring it on themselves... Just as what was stated above, the aisles are narrow... So, be prepared to have hurting ankles if you cannot follow a simple instruction and MOVE TO THE END OF THE ROW!!!!!!!!!!!!!!!
Oh, and as a side note, I'd do my best to not kick a kid, but I wouldn't try to avoid the arrogant adult who should know better...
