How would you answer someone accusing christianity of exclusivism?

Christian exclusivism is where people of the Christian faith believe that their values and belief systems are the only relevant and true beliefs one should align themselves to. A person who may perform this may tell someone that they will go to Hell if they do not accept Jesus Christ into their lives. This is not all people o the Christian faith who say this; Christianity can, however, appear exclusive, as it states in its Scripture that the Christian god is the only god.
