Communities, whether they are real life or virtual, live and die largely based on whether they are the kind of place people want to hang out.
If the community is filled with thoughtful, intelligent people who contribute to the community it can thrive and be a wonderful place.
If the community is filled with anger, divisiveness, and pettiness, it dies.
Bearing Arms and the associated Second Amendment Supporters Facebook page will be the kind of community where people will be able to debate, share ideas, engage in constructive criticism, and respectfully disagree.
Those who cannot comport themselves with a reasonable level of civility will find themselves invited to participate elsewhere.
