Well there's no "proper" way to skip through the endless walls of text, but there two ways you could just play missions. Go into the tech room and to the mission simulator and when you have campaign missions selected, press Shift Ctrl S (all at once) and it will temporarily unlock all the missions in the campaign. In general, mission filenames ending in B and D are actual space sim gameplay ones.
Alternatively, set your difficulty to "Very Easy" and when you're in the campaign mission select map (the one with the fancy scrolling buttons), everything will be unlocked there. (But you'll be stuck in Very Easy)
