2022: Heng speaks about repealing Section 377A and maintaining harmony
DPM Wong also gave his assurances that the definition of marriage would not change under his watch, should the PAP be re-elected in the next GE. A new balance would not be possible if people insist only on pushing across their views or venture into polemics. Singaporeans by and large cherish the harmony and common space that we have. Even for difficult and evocative issues, parties have approached dialogue with respect, restraint, and rationality.
Arriving at a new equilibrium on S377A will show that even for contentious issues, there can be room for accommodation. But we all need to do our part to carry out dialogue in a way that will move society forward and call out those whose actions undermine the harmony that we so treasure.

"But what is important is that for certain issues where views are so different, it is for us to build that social consensus. And over time, views may evolve. But what is important is not for groups to go on the confrontation, because when we do, then I think the views will be even more polarised. I believe that views will change over time, and we will have to deal with that. And even then, it is not the case that everybody will change their views."
