A little back and forth between fans is normal. This NEEDS to occur. This is normal. Soccer is a way more polarized than other sports. In America it's been pussified.
Re: OT - Should MLS change there Season to winter? If they don't understand what Apertura and Claustra are, we could always just call the two halves what they really are: Fall and Spring. That's been done here before, waaaaaay back when the original ASL played a Fall/Spring schedule.
There are a couple leagues that do this. I know for sure it's done in Serbia, I'm not sure about Croatia tho because I really don't follow them.
Re: OT - Should MLS change there Season to winter? Well I don't suggest that we use Apertura/Clausura as they are in spanish but we can some translate. Opening/Closing.
