I'm not sure complex political issues is what this thread is for. But anyway.
The cartoons that the French teacher was killed for showing stem partly from a Danish newspaper back in 2005, and since republished by Charlie Hebdo, along with other cartoons.
Back then some Danish imams informed other clerics in Muslim countries about it to cause an uproar, which happened.
Danish products (like cheese) were boycotted and flags burned. There were even leaders of state demanding the prime minister to make the newspaper retract the images (clearly not knowing how a democracy with free press works).
Now the case has flared up again, and it seems like a good opportunity in these trying times to find a scapegoat
and accuse the French state/Macron of being islamophobic.
It also comes after Macron launched "an attack" on extremist/separatist elements in the Muslim communities.
French president Emmanuel Macron has introduced plans to defend secularism against the threat of "parallel societies" emerging within Muslim communities. Schools must "train citizens, not believers," Macron said.

In Muslim countries it might be easy to spin such a story into an attack on Muslims in general.
In case you're not aware, depicting the prophet is a serious offence in Muslim majority countries, and something you never see there.
You say they "were most probably imagined". Yes, but not depicted.
After that you go off the rails and talk about taxes and flat earthers. No comment.
