Why does swaha's father in law hate dancers?

Or anything attached to thamasha...it is not exactly bad. How come he hates them so much that he even disabandoned his own brother?

I meant Swara**

Well ever Since Ana sahibs brother Saya jee chose the path of tamasha and lavni in front of Ana sahibs honour, meaning that Ana sahibhad had fixed Saya jis marrige with some girl and on the day of his engagement saya ji left Ana sahibs house which clearly proved that Saya ji does not care of Ana sahibs honur or decision what so ever... Ana sahib has since then somehow connected tamasha and lavni with dishonour and disrespect... he hates the sight of tamasha karne log or lavni karane wale..... I hpe iam making sense..:)

a watery excuse- i think it would be a darker secret where Anna sahib must have loved a lavani dancer in his youth and she may have decided to leave him and not care for his feelings!!!
