Explain what you are objecting to and why you find it objectionable.
Perhaps they're mad as hell that we don't have sufficient gender diversity in our IT industry.
On top of that, the low pay and asshole students make teaching a very thankless profession. That's why most people who have an ounce of brains do something else. If we would treat our teachers better we'd probably get a better quality of people into the profession.
And then there's people like yourself who think it's the teacher's fault their spoiled kids aren't learning anything. I'm concluding this by your third sentence where you suggest that all of the existing teachers are of low quality. Your little snowflake couldn't possibly be at fault, could he/she....must be the teachers.
