By committing a felony, felons have harmed their community and shown a lack of respect for it. Giving felons the right to vote enables them to have a say in what happens to the very community they have harmed. Only citizens who want the best for their communities should be able to vote. Felons have proven that they do not value the community's wellbeing. For this reason, they should be disenfranchised.
Felons, once they have served their sentence, have repaid their debt to their community in the eyes of the law. There is no reason to continually punish them, especially when it blocks their progress in reintegrating themselves into society and discourages them from becoming invested in the community. This argument also assumes that felons are beyond change. It argues that because felons disregarded their community's wellbeing in the past, they will retain their disregard for the rest of their lives. Felons are capable of becoming upstanding citizens and leaving their past behind.
[P1] Felons have clearly shown their disregard for the community's wellbeing. [P2] Only citizens who value their community and the common good should be allowed to vote.
Rejecting the premises
