Did you actually see men brutally beating women on the show? Was it a regular occurrence?
You do not see this in the UK, as it is not culturally acceptable to regularly show men beating women on TV.
There may be scenes of domestic violence, but it is dramatised to show it is unacceptable, which is not the case in Thailand, where it is regular, often validated and considered acceptable due to the victim 'cheating'.
Thais are far more likely to mimic what they see on TV than people in the UK.
