Is meditation a STS act?

[βαθμιαίος]

So I'd say that it's not 'not loving self' which is STS polarized, but repression of love for self with regards to green ray.

Which may well be what the original poster was trying to say. Your clarity about the role and power of second-distortion love has been helpful, though, so thank you for that.

Just as it can be said that the STS ignores or lacks focus on green (and blue) disciplines of the personality, we can say that the STO lacks focus on orange and yellow disciplines of the personality. Each ray is an opportunity to experience the 2nd distortion, or to actualize oneself from the creator as co-creator. We can even say that the only reason that STS has power over the STO, in some circumstance, is due to the STO entity's lack of love (and vice-versa). Indeed the STO entity that is subject to the power of the STS entity is one that ignores and does not accept themselves with regards to what is offered.

STO does not necessarily neglect orange and yellow rays. Many who are attempting to be STO do neglect them, but it's not a necessary part of the path. Witness Ra's description of Carla's energy centers (38.5) and of Albert Schweitzer's (34.10).
