Context:
She's a new Thai idol that was announced to debut in K-pop. Her family are entertainers/celebrities and openly royalist. They support the monarchy - Thai people are saying her family is supporting a 'dictatorship'. You can read more about Thailand's political situation to get why this is a problem.
She stated that her idol in life is her father. Her father is considered to be problematic. It created a huge buzz because of it.
Comments under the post range from valid criticism, to saying 'aren't K-pop companies adding foreign idols to attract, not repel fans from their home country like in thi scase?', to, "are they trying to attract foreign ultranationalists", to "#DICTATOR_OUT", to "how can the company be so careless, ignorant, etc.".
It's not good.
