I admit to saying 'Jesus Christ' etc without thinking as not a swear word, but so realise I shouldn't be saying it as it's not nice. There's no escaping swear words though kids hear them everywhere, just need to explain where and when they can or can't say them
To people of faith, blasphemy is far worse than swearing, though - not just 'not nice'. It seems like a double insult when people who would likely balk at the thought of discussing thoughts or opinions about the object of your faith nevertheless use that as their go-to whenever they want to express disgust/hatred/anger/whatever. If a faith/belief system means nothing to you personally, then fine; but just ignore it as irrelevant in your life. Buddhism is simply not a part of my life, so it wouldn't ever occur to me to shout ''Gautama Buddha' as an expression of anger. Even if I were somehow minded to do that, I still wouldn't, as why would I want to aggressively upset Buddhists for no reason at all with an offensive throwaway insult?
If you must, at least shouting a 'regular' swear word - most of which tend to revolve around defecation or sex - is 'neutral' and not (originally) calculated to insult or offend anybody's sincere personal beliefs.
If people everywhere routinely used the name of your Mum (or somebody else you consider very precious to you) whenever they were disgusted or angry about something - hit their thumb with a hammer or stepped in some dog poo - and their very first instinct was to screw up their face and shout "Edna f*ing Philips", I can't imagine most people wouldn't have an issue with that.
To clarify, I'm saying 'you' here in a general 'including everybody' sense - not referring specifically to you
