so what is everyone's stance on the whole..."He's your Master, He has the right to ignore you safeword" thing?

i've many a Dom say that is you are a complete slave, as in your Master has total control over you, that includes the usage of a safeword. and whereas you can still by all means shout out your safeword, your Master would have the right to ignore it if He felt it was ok to do so.

now i kinda understand the mentality behind this....but how does everyone else feel about this?

btw...my safeword is blue clues....because i figured if i was using my safeword, i was going to need something to make me laugh.....and how can you not smile at a bouncy blue dog?
