Should the government spy on the online activity of it's citizens?

No! The government has rules that it needs to follow, rules put in place to prevent it from gaining too much power. One of these rules is called The Fourth Ammendment, it states: "The right of the people to be secure... against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause..." (an abrviated version of the fourth ammendmant of the constitution) Filtering through it's entire citizens web history is not in line with respecting our right to be secure against serches with out probable cause and a specific warrent for what there looking for. When the government posseses the ability to search through our personal lives and our data we hold on the internet, that is an infringement on our personal privacy and on the constitution.

The government has no right to infringe upon the constitution and especially not upon the liberties of its citizens.
