A lot of these complaints stem from never having seen politicized spelling before.
With regard to grammar, some critics have run tests on our writing and shown others that it's not as bad as they think. Nonetheless, we have to admit that the corporate media has the advantage of hiring multiple people full time to do editing and proofreading. A typical magazine article might have three writers and four editors. At MIM we cannot do that. The solution is not to whine but to join.
On the plus side, MIM's lack of professional staff makes MIM more effective as an outlet for change than charities or political groups with overheads in staff. MIM's money goes right into doing things.
Relying on amateurs in our work is necessary because of the whole structure of the class struggle. No one has figured out how to make a profit selling the revolution. Bands like Rage against the Machine have only figured out how to do it for a piece of what needs to be done.
We also make no bones about using amateurs in our art and graphics. We have no alternative and our basic attitude toward this question is an important aspect of materialist philosophy. If you can do better in anything we do, please go right ahead. If you would submit good art to replace bad art, you might even find MIM willing to do that. It's not that we do not want to improve. It's just that we insist on using the best of what we have on hand and deride all other approaches as nihilist immaturity.
