Finish teachers blame fasting for negative impact on learning

If Islam was to be practiced to its full meaning as it was meant to be there would be no problems whatsoever but as any other true faiths people mixed it with their cultures but coming back to the complains from Finish teachers, I do understand their concerns, but it has nothing to do with the fasting of some of these youngsters, the problem is, yes some of these kids feel they have the right or gave themselves the right to bitch about it and let it go out over their teachers or their schoolmates, in their own countries where almost the whole school and its teachers fast everyone is in the same situation, who are some of these kids are going to complain and nag to when all are fasting, no one, and they dont see other school mates drinking eating and the rest of it and feel like they are the only ones who are "suffering" and then take their own restriction over others and then the whole point of self restrain loses it meaning and with less concentration in the classroom they will eventually stand out and not in the right way, another point these Finish teachers should know is, then how come these same kids do just as well in their own countries during the holy month of Ramadan where there is many times hotter than in up in north Finland, so the question is not kids fasting and their learning abilities suffering, they are suffering from something else, perhaps too much freedom during their time at school, monkeying around, something todays youngsters feel they have this freedom do do whatever the hell they want and if someone elder corrects them they are told by these same teachers to call the cops on them, call the authorities on them, on their parents, I remember when I was dragged to Sodom the first thing our teachers told us was how to call the police if our parents disrespected us, these Finish teachers shouldnt complain now, they asked for it, this is part of the problem,
