What are some topics I could make a persuasive speech about that relate to freedom and equal rights?

As an assignment, they are basically wanting you to state
a thesis argument or claim that fits into the subjects you've chosen.  While I can't
write your assignment for you, I can give you some topic suggestions that fit into the
category of freedom and/or equal rights to get you started.  Keep in mind, you may not
agree with the position that you are arguing in your
speech.

1)  Gay Marriage - you can state a claim either for
or against the right of homosexuals to marry, framing it either as a question of equal
rights with heterosexual couples or as the right of straight couples to have marriage
defined and protected.

2)  Immigration - one could argue
that immigrants, legal or not, should have equal rights in the workplace for minimum
wage, limits on working hours or protection from unsafe working conditions.  You could
also argue that people should have equal rights to seek jobs and better, safer
conditions for their families.

3)  The Westboro Baptist
Church - this is the group that protests funerals for American soldiers killed in war as
being punishment for America tolerating homosexuality.  There was recently a Supreme
Court case about this, and you can ether argue they have the right to free speech or
that this should be restricted.
