If it's obviously a deliberate foul, like tugging back or a deliberate trip, then red card. If it's a genuine attempt for a winnable ball or an accidental foul/collision, then a penalty and maybe a yellow.
In most cases it's pretty obvious which is which.
It should be, but the compulsory red card was brought in precisely because defenders would take the chance on the colour of the card in order to stop a goal being scored. And then you'd have people ranting that it ought to have been a red and wasn't. Truth is there's no ideal way of handling this, you're always going to get anomolies.
I still don't believe BT Sport are biased - but they didn't have a great night last night.
