em dashes thanks for pitching in on the united states article i noticed that you added spaces around a couple of em dashes that actually goes against our manual of style em dashes should not be spaced also whenever considering such a stylistic change look through the whole of the article to see if the present style is applied consistently in the case of the united states article unspaced em dashes have indeed been applied consistently if you do find that the style is consistent there should generally be a compelling reason not just a personal preference for any change regards
