Davy asked:

Is it unethical to try change a persons morals?

Are all ethical theories relative, i.e. Kantian, Utilitarian etc. or is there only one true moral theory?

============

If you really object to someone's morals isn't it unethical NOT to try to change them? ... within the
limits, no doubt, of certain civilised constraints, good manners, etc., or whatever is appropriate to the
nature of the particular issues at stake and your relationship with the other person? Conversely, if you
believe, or come to the conclusion, that it is neverethical to try to change anyone else's morals, then
wherein, would you say, does the point of your own morals consist (whatever they may be)?

Rather than just trying to answer these questions at the level of abstract generalities and principles,
can you think of a range of specific cases of your own, think your way through them... and see what
conclusions you come to?

How far should we be prepared to go in trying to 'change' the moral views of someone whose views
differ from our own?

You will probably agree that murder is going too far, but anti-abortionists and animal rights protestors
have in the past resorted to terrorism. At the end of the day, what matters is not that the other person
has the objectionable moral views but rather the fact that they are prepared to acton those views. So
if you can't win the argument, then consistency with your own firmly held moral beliefs demands that
you take the next logical step and resort to violence.

Or?...
