You a big supporter of the Viet Nam war? Most of the country wasn't.
Canadian immigration statistics show that 20,000 to 30,000 draft-eligible American men came to Canada as immigrants during the Vietnam era. The BBC stated that "as many as 60,000 young American men dodged the draft."
Even though there was some opposition to the draft even before the U.S. direct involvement in Vietnam, the conflict saw new levels of opposition to the call-up. As American troop strength in Vietnam shot up, more young men of call-up age sought to avoid or delay their military service and there were some legal ways to do that. Men who had physical or mental problems, were married, with children, attending college or needed at home to support their families might be granted deferments. It is worth noticing that many men received deferments were from wealthy and educated families. Prominent political figures accused of avoiding the draft includes Bill Clinton, Joe Biden and Dick Cheney.
While President Johnson ended marriage deferment on August 26, 1965, some men claimed to be homosexuals while many others chose to flee to a neutral country such as Canada and Mexico to avoid the draft. These people were derogatorily referred as “draft dodgers” – a term made popular during the Vietnam War.
In the beginning, many people looked at “draft-dodgers with contempt as being “cowards”. As American casualties rocketed up while the U.S. could not see the light at the end of the tunnel as claimed by its government, the conflict in Vietnam became more and more unpopular. As a result, more people got involved in the anti-war and draft resistance movement and backed these draft-dodgers.
