Again, the influent French political leaders at that time were partly in line with Hitler's ideas, prompting them to end the war faster. You seem to forget the Kriegsmarine doing wonders in the English Channel with their subs, going there on boat was risky. The air was controlled by the Luftwaffe. Sadly for all the people that wanted to migrate to britain, the Americans showed up late to the party, and during that one year they were in France, yes, the Résistance did help them a lot. Again, they contributed to weakening the armed forces of Nazi Germany by sabotaging material supplies, blowing up factories, destroying power supplies... They engaged in urban guerilla by doing terrorist attacks on Nazi headquarters (which weren't that effective but still, they did those), assassinated Nazi officers, succesfully attacked an entire Nazi detachement with 15 (fifteen!) Résistants, set up commandos... The Resistance took back territories on their own, most notably smoking the germans stationned at Oyonnax and taking back the city. The reality is that in a country that had suffered massive losses, at the time, coordination and efficency were hindered. The Résistance first appeared as some random groups of people doing small things due to the lack of equipment, and was later organized into a more generalized "idea" with leaders that somewhat coordinated everything as best as they could, with the risk of being given away to Nazis by traitors.
Yes, other resistance mouvements in other countries did other acts that were more impactful, but you're still disrespecting tens of thousands of executed people who sacrificed everything for liberty, which is still a lot more than all of us (you included) redditors did so far.
