A person can have a secular outlook; however, being secular is not a role. Hence the question Show me a 'secular' person, and I'll show you a liar may not be apt.
Having a secular outlook does not mean that he can not be a religious person. Even science never deprives anybody of their religious beliefs, specially in the realm of unknown.
Being secular definitely means accepting secular constitution and not demanding to make it a religious state, Hindu or Islamic. It definitely means accepting supremacy of civil and criminal law. It definitely implies accepting all are equal in front of law irrespective of economic or cultural strata or religious denomination, or political nomination. Secularism is our best bet to attain equality in the best sense of the word.
