I have a rant about kiddush Hashem.
Kiddush Hashem is when it is evident that following the Torah makes you act in a good way. This brings kavod to Hashem who gave us the Torah.
Often, Rebbeim and teachers of younger students will tell them before going on a trip that they should behave so as to make a kiddush Hashem.
This is absurd. If you act properly in order to make a kiddush Hashem, you are basically saying that it is not following the Torah which makes you act that way. Rather it is your desire to trick people into thinking the Torah is good which causes you to act that way.
Tell the kids they should behave because it is the right thing to do. That will be a kiddush Hashem.
