Many Jews define keeping kosher as something that only the Orthodox do properly, yet they hold fast to their own dietary choices.
Whatever you do is fine. For you. Don't let someone else tell you that you are more or less Jewish based on the food you eat. You may be more or less observant but food doesn't terminate your Jewish identity.
I do believe that every Jew by choice should consider the dietary laws and take on the ones that are authentic to them. Pausing to think about what you eat is part of living mindfully. Much of Jewish law equips you to lead a life of thoughtfulness.
