I am not a KSG fan but an Armaan fan, but would always want to see KSG as Armaan. In other words, I am a fan of KSG's acting, but not his fan.
So I see myself as not being biased towrads, or against him.
I feel that it is his personal life and we should not discuss it because we don't know what ACTUALLY happened. If it was for sure that KSG cheated on his wife, then I would be the first one to say that he is wrong.
However, I would still not bring Armaan into this because that is his professional life, and career, and if he is good at his job then why would we mix his reel like and his real life together?
I say that KSG fans shouldn't overly and overtly defend him, and neither should other people call him "cheater" etc, because we have no idea what happened really.
Also, IF is a very clean place and topics as such can lead to bashing, which is not right, again because WE DON'T KNOW THE TRUTH.
ps I hope this doesn't sound mean, I am genuinely trying to answer your question :)
