I agree with you on this one.  This loophole should be fixed.  Attaching the apology to this bill was designed for political gain with no expectations of the bill passing.  
If the Liberals voted against this, as they did, they look bad.  
If they accepted it as it was and they apologize and look bad.  
If they demand the apology be taken out of the bill, they look bad.
The last option is the one they should have taken.
This loophole needs to be closed.
