Filmmaker Tahira Kashyap, whose actor-husband Ayushmann Khurrana plays a gay character in the upcoming 'Shubh Mangal Zyada Saavdhan', has said it's important to be in love irrespective of the gender. "The idea is to celebrate love, and the day we stop thinking and about whether it's a love story between...boy and...boy, or...a girl and...girl, we'll have developed as...nation," she added.
