Discussing the differences that DC experience is a great way of getting perspectives into their minds.
I think poo jokes are just as funny as the next person; however, it is close to the knuckle when its targetted at a child that's feeling uncomfortable about that, and a decent teacher will realise theyve totally missed the mark and follow it up with something reasonable.
Telling people what a big personality you have,
sounds arrogant, and foisting inappropriate [personalised] jokes on children that obviously haven't appreciated it, plus pushing a child into a desk, is all adding up to a teacher who isn't clear on boundaries.
AFAIK you do lay your hands on children in any way, and I'm not someone who thinks a child who's hurt and is crying shouldn't get an arm round a shoulder or for very young ones sat on a lap for a cuddle. Showing yourself to care is boundaries as is being a boorish teacher who's up himself and pushes his pupils around and make crude pointed jokes at others expense.
It all hinges on the heads boundaries for his teachers. As a new teacher that he's probably recruited he's fairly invested in wanting/needing this to work out.
Have you spoken with other DMs about him? Have you heard any other derogatory remarks/incidents?
Tbh I would be raising it direct with the teacher to gauge their response, and their side of events also. If you have a shy and unsure DD it can feel overwhelming and scarey, and he's needing to moderate ang regulate himself as not all will respond well to his style. He needs to recognise that if it's affecting children's access to learning.
You might find, on speaking directly to him that he's a completely reasonable sort, and sensitive to his pupils reactions. Him saying he's a big personality should be accompanied by an acknowledgment that his style, anybatyle that's strong, is going to rub some up the wrong way, and need insight on his part to be flexive around his learners styles.
If he's continually targeting pupils for crude jokes, pushing individuals into tables and putting his 'big personality' above the needs of his pupils, someone does need to do some moderating for him! Enforce some bounadries and regulation.
