Why does anyone at club level play 1... e6?

I have mated French players probably 3-4x as often as Sicilian players even. The opening is basically saying here go ahead and attack my king for free. Don't French players get tired of getting mated?

Not saying I don't lose to French but always happy to see it

Why not? I'm not particularly fond of the positions I've ever had in the French, but I also haven't ever really studied the opening. 

At club level, opening choice has very little bearing on the game outcomes.

The French is very solid and offers good counter attack opportunities for black on the Queenside. The key point for black to remember in the French is to keep a knight close by the king, otherwise checkmate will indeed come pretty quickly.

I personally have won many games as black by getting my rooks on the c file and penetrating decisively into whites queenside.

My assertion for why not is you get mated often with weak king safety. Its much easier to attack than defend especially at a club level without extensive preparation.

At the club level, almost all games are being lost to tactical motifs. Yes, some can be influenced by opening considerations and positional motifs and some may be harder in general to play or defend against. But it normally comes down to blunders made after the opening phase and is often not something that had anything to do with the opening choice.
