Do Christians impose their views?

How many times have we heard the complaint that Christians are guilty of imposing their views on non-believers. When Christians refuse to support same sex marriage we are accused of imposing our views, likewise when we oppose Sunday opening, and even when we seek to carry out public evangelism. Every time a Christian speaks out against unbiblical laws and practices they are met with the accusation that they are forcing their religious views on the rest of the population. Is this accusation true; are Christians really guilty of forcing their beliefs on other people? Is same sex marriage prohibited in Northern Ireland because Christians impose their views on others? Are people in the United Kingdom being forced to accept the views of a minority of Christians?
